Hand-Loaded Nosler AccuBond LR 142 grain in Ruger American Predator in 6.5 Creedmoor

The G1 ballistic coefficient for this bullet is .719. The fact that it exceeds 0.7 is world class long range capable of delivering game killing energy at over 600 yards for the 6.5 Creedmoor.

Tech Talk – It has been said that the bullet has a secant o-give and needs more room away from the lands when chambered than your normal bullet but having said that, it does not take from accuracy on bullet jump.

A few days ago, I loaded up some Nosler AccuBond LR’s in 142 grain with IMR 4350 and W760 Powder specified by Nosler in my almost new Ruger American. I used 41.5 grains IMR 4350 and 40.5 grains of W760 powder, max loads. I selected the powder because they were among the fastest at the muzzle and geared for delivering lots of energy at longer ranges.

The cases were Nosler Custom and the primers were CCI BR2’s. Cartridge overall length followed the Nosler Manual of 2.805 and they fit the Ruger magazine perfectly and fed perfectly.

First IMR 4350 cold shot with the Ruger American was 1 inch higher than subsequent  4 shots. Accordingly, I eliminated the cold barrel shot from the group. If I included it the spread was 1 1/8 inch and if I eliminated it the spread was 7/8 inch.

Estimated velocity out of the 22 inch barrel was around 2670 fps after subtracting 60 fps and the 2 more inches in the Nosler manual using a 24 inch barrel compared to the 22 inches of the Ruger.

The W760 Powder shot 1 3/16  five shot group with an estimated velocity of 2610 fps accounting for the shorter 22 inch barrel.

Examination of the primers looked normal and extraction was easy. These loads were terrific.

The results indicate that this grouping for IMR 4350 is terrific for shots in a 6 inch circle at 600 yards. Further that the energy for deer suggests 650 yards where 1000 ft-lbs was calculated and the velocity was 1802 fps. Windage at 90º moved the bullet 28 inches at 10 mph crosswind. That is a lot! Quartering crosswind of 14 inches. The shooter would have to adjust for the crosswind or get closer to the game, a much better scenario.   At half that distance 325 yds the shooter would only be off by 6 inches in a 90º wind and have elk killing energy of 1500 ft-lbs.

Below is the Ruger American Predator. A great affordable rifle for anyone!

The Scope was a Leupold VX-3. See them at https://www.leupold.com/search?q=vx3

 

In a perfect world, early morning and just before dark usually offer little wind for those longer shots.

Killing game cleanly is the name of the game!

Good Hunting!

Looks very positive at this time! The process is under way!

 

A Quick Walk with Ruger American 6.5 Creedmoor and Ruger M77 African in 375 Ruger

OK, it’s August and it is time to get the cobwebs out of my Gun Safe.  My two most accurate rifles for the price are the Ruger American Predator in 6.5 Creedmoor ( around $400 retail) and my Ruger African M77 in .375 Ruger ($900 retail). Today I am about to shoot them when I met fellow rifleman Joe Chicarello shooting his bull barrel .22 Long Rifle. I am sure he was having a great time and nearly done shooting when I arrived at our club range. Joe was easy to talk to and we resonated on shooting and safe handling practices. He has a Browning .223 that he has yet to shoot due to a scope ring issue. I hope you get the rings soon Joe! I invited him to check out my Ruger Rifles. He has never shot any of them so after putting a round down range in the larger bullseye at 50 yards off the Caldwell bench rest with the 6.5, I invited him to try it. I said, it does kick a bit more than the .223 so my bullet hit the center target just off the dead center by a half inch. I put three rounds in the clip with an open bolt and got Joe ready to try it, again at 50 yards, but to shoot a smaller target in the upper right corner. The scope was my Leupold VX-3, a superior hunting scope ready to hunt anywhere in the world

So he shot and I put  my binoculars on it and grinned. Joe it is dead center in the bull, I said excitedly. Kicks more than I expected, he exclaimed. So I put a neoprene pad on his shoulder and he fired again. Just that one hole there, I observed. How did the pad work? I asked. Much better, he added. You’ve got another shot left Joe. So he took aim again and fired. He said, “maybe I wiggled on that one!” Accordingly, I observed that same one hole there. Lets take a look Joe  and see what’s up. The range was made cold and we walked to the target.

Arriving at the target, here we are looking for strays but when we looked close enough there was one tri-cloverleaf hole in the upper right target. All the time Joe said, I’m a bit shakey.  I assured him that was not the way the bullets saw it,and congratulated him on such fine shooting.

In my testing this rifle a year ago, I shot 1/2 inch groups at 100 yards with other hand loads in the Ruger American and was thinking these were hand loads too but not so. They were right out of the Hornady Precision hunter box which features ELD-X™ bullets (Extremely Low Drag) that I used this past summer in a different rifle where I popped 8 inch balloons at 1000 yards at the NH Sig Sauer Academy with my son Jason.

Then I shot a .375 Ruger light hand load (2200 fps) of speer 235 grain heads out of the stone cold gun and it hit 1 7/8 high from the dead center. I invited Joe to try but he said he was done. Perhaps a bit fearful, I dunno. Doesn’t kick any more than my T/C Encore muzzleloader with 100 grains of Pyrodex I said. Nope, Joe wasn’t ready.

So I proceeded to put 2 more shots in the center bullseye using the same aiming point. If you look close you can see my first shot from the 6.5 in the center bull as well.

All said and done that was a nice short walk in the park (range) and made a new friend I too. I asked his permission to use his name in this article. Of course, he said.

Good Shooting!

Savage 12 Palma in Mid Range Prone F T/R Match by Jason Hale

Since I’ve started long range competition, I’ve been exploring ways that our readers may enter the sport at a reasonable cost, of course you can select your hunting rifle in your safe, but if you become serious, the modifications will start.  Enter the Savage Precision Target Rifle Line.  We reached out to Savage and requested the 12 Palma due to it’s unique stock configuration and caliber choice.  Most of the Precision Target Actions (PTA) have a screw spacing of 4.41″, however the 12 Palma has a screw spacing of 3.44″, the reason for which I am not sure.

To learn about Palma Rifle competition Click Here!

All PTA’s accept large shank barrels from your favorite Savage pre-fit barrel supplier.  What I really liked about this configuration was the adjustable stock and 3-way adjustable butt-plate.  See below for some stats on the rifle.

Savage 12 Palma Match Rifle

One thing you’ll notice right away is the odd twist rate of 1:13″.  This twist rate is indicative of the intended bullet that was intended to be used, 155-156gr bullets.  As soon as I received the rifle, I quickly picked up a rail for it and mounted the 7-42X55mm Gold Ring Leupold Competition Scope & Shade we are testing (Outstanding Scope) and ordered some 155.5gr Fullbore bullets from Berger. I recognize that this was not the set up that the rifle was designed for, but the purpose of testing was to determine accuracy potential of the rifle. You can tell that this was really meant for iron sights as you can see the front sight cut near the muzzle of the rifle so that you can clamp-on front sight tubes.  In the pictures below, you’ll also see the 3-way adjustable butt-plate which is fantastic for customizing the fit of the rifle to a specific shooter.  It can be adjusted for length of pull, cant, and height.  I made some minor adjustments to the cant and height, and left it there.  I could have spent more time on tuning the stock, but didn’t.

Once the bullets came in, I took inventory of the powders that I had on hand and selected IMR 4166 which is supposed to be temperature insensitive much like Hodgdon Varget and got to putting some test loads together.

Following a break in process, the rifle immediately demonstrated it’s accuracy potential.  Being limited for time, I settled on a load of 45 gr of IMR-4166 with a COAL of 2.800″ which was limited by the Palma Chamber, which has a very short throat.  See the group shot below.  Not bad at all for an afternoons work.

In all fairness, if this was my rifle I would have spent more time tuning to reduce Standard Deviation and Extreme Spread of velocities, but given the limited distance (600 yards), vertical dispersion would not be as bad as longer distances.  Wind would be more of a challenge.

The day of the Mid-Range Prone match, I was excited to take the rifle out and see what it could do.  I knew that with good loads, it would likely out shoot me, which is a good thing.  The prone match included 3 strings of fire at 300, 500, and 600 yards, with 15 rounds for record with unlimited sighters at each distance.  The wind picked up during the day peaking with 10 mph switching winds during my 500 yard string after settling into a more predictable rhythm for my 600 yard string.  Overall I was pleased with the day, but was a bit frustrated during the 500 yard string being behind on some wind calls that cost me more points than I wanted.  I was only one of two F T/R shooters there, the other being a good friend and great shooter Barbara Lamb, she only dropped 3 out of a possible 450 points for the day, which is fantastic.

Barbara Lamb scoring for me, while Art Lamb (in line for saint-hood, in my mind) was graciously scoring for all on our target.

My scores were 143-0X (300), 131-0X (500), and 144-2X (600), with an aggregate of 418-2X.  The rifle shot great for the little time I put into load development.  I am sure that I could have done more tuning, but in the end I needed more time on the rifle to improve.

One thing I can say, is that if the other rifles in the Savage 12 PTA series shoot similarly, you can’t deny the value, considering the cost of most custom F-Class rigs being between $3000 and $5000, or more even.  Great bang for your buck.  If you’re interested in a quick and relatively inexpensive upgrade that can be further modified easily in the future, check out Savage’s M12 Precision Target Action line.  If you want to start from the ground up and build one, you can purchase an action from Northland Shooters Supply. I’ve done plenty of business with Jim; they’re awesome!

Shoot Straight and Shoot Often!

See you at the range!

Lots of Learning: Match Results, Mystic Precision Bipod Review, and Leupolds Gold Ring VX-6 7-42 x 56mm Competition Scope with CDS

Testing new gear in a long range match.

I had an interesting match last Sunday (28-May 2017). In my previous article here I announced the intent to test some new gear in a match.  I learned a great deal about changing gear before a match, but the biggest takeaway is: If you change gear and don’t practice with that new gear at competition distance, you should be prepared to have a few accuracy surprises that happen once you start punching holes in paper.

First Impressions: Leupold Gold Ring VX-6 7-42x56mm Competition scope with CDS

First things first, the glass is just gorgeous to look through.  The morning of the match I had it dialed up, but as the day went on and the mirage started to intensify I had to back off a bit to 32X.  I also realized that I have some additional adjustments that are necessary for eye relief when in the prone position.

Learning about the impact of new gear: Leupold graciously supplied rings for our testing that would mount to any rifle for us to test as long as it had a picatinny rail.  The particular issue with my rifle is that I did not have a high enough comb nor adjustable comb to accommodate the ring height.  I knew this going into the match but honestly didn’t think that it would matter that much, but it definitely did.  The difference or variability  in cheek pressure on the comb had a huge impact elevation control and lead to uncomfortable body/head positions and a poor score.

First Impressions: Mystic Precision MPOD Bipod

While zeroing the rifle the bipod was like a rock, on the line at distance, however, my “squeeze bag” style rear rifle rest was not cutting it.  In order for the bags to work effectively you need to apply consistent downward force with your cheek and squeeze the back to it to remain stable.  If you can’t apply consistent pressure with your cheek, then having a repeatable position is difficult, and my score’s definitely reflected that; my worst for the day was below along with my typical score from last year.

Score last year with original set up.

Score with different set-up (Different SCOPE/BIPod).

I will note that at the time of the string of fire, a shot was marked as a miss, but following my string and talking to Art Lamb, who was scoring for me, he informed me that one of my rounds was subsonic at 600 yards and he later identified the impact in the white portion of the target, so not a miss, but perhaps a 5 or 6.  Not too happy about that; I did notice that my barrel was getting a bit hot from the quick string of fire, so I don’t know what happened here.  My next purchase is a good old kitchen timer to make sure I don’t go too fast and heat the barrel up too much.

On a humorous dad note, my wife called me and informed me that my mother in-law was at our house with the kids needing to put my youngest son down for a nap.  The only problem was that I locked all the doors and she did not have the key.  Rather than breaking into a fit of twitches after my horrible match, I calmly let it roll off my shoulders and trekked 4 miles down the road and let her back in.  It’s good to live close to the range. Looking back and doing some diagnostics on the poor match, I realized that I should have changed bags over to one of my fixed rear sand bags with the bipod.  The toe of my stock is angled so that elevation corrections can be as simple as moving the bag fore or aft of the buttstock.  We always learn.  I’ll be better acclimated to the new gear next time.  Next up; a barrel swap will take place to the new Shilen 6.5 Creedmoor Match Barrel and we’ll do some F-Open work with a front rest for a match on 17-June.  I love the Savage Barrel Nut!! It’s so easy to swap barrels!

Until next time…..

See you on the range!

New Nosler RDF Bullet Initial Testing Begins by Jason Hale

In my previous article, I explained my intent with regards to load testing I wanted to complete in my current economy match rig, which is a Savage 10 repeater action, re-barreled with a Criterion 28” Stainless Select Match bull barrel chambered in .308 Winchester

Nosler supplied us with some brand spanking new .308 caliber 175 grain RDF bullets to review. Nosler intends to make this bullet a premier Competition bullet.

Quote from Nosler website

RDF Bullet – ( Reduced Drag Factor )

Flattest Shooting Match Bullet On The Market

For those wanting to squeeze the most performance from their competition rifle, Nosler’s new RDF (Reduced Drag Factor) match bullet line is the ideal choice. 

Nosler’s RDF line was designed from the ground up to provide exceptionally high BCs, which create the flattest trajectory and least wind drift possible. The keys to the RDF’s outstanding performance are Nosler’s meticulously optimized compound ogive and long, drag reducing boattail, which make handloading a snap and create an incredibly sleek form factor.  RDF bullets also have the smallest, most consistent meplats of any hollow point match bullet line, so there is no need to point or trim tips. 

Highest B.C.’s, smallest meplat, tighter groups – Nosler RDF.

Unquote

 

I was excited to see if the bullet would fit seamlessly into my current loading diet of Varget powder.  The accuracy results were pretty good, but at velocities that were a bit on the slow side unsurprisingly; great bullet, but as the data demonstrates, the bullet/powder combination choice may not be as accurate in my barrel.  I’m pretty sure that if I continue to experiment with powders that I would find one that would be extremely accurate with the Nosler RDF with my barrel.

175 Nosler RDF with Hodgdon’s Varget

Charge Weight Group Size Velocity
40.0 0.784” 2445
41.0 0.435” 2491
41.5 0.756” 2546
42.0 0.943” 2591
42.5 0.851” 2629

Bullet distance to rifling: 0.015”

Following this first test I decided to back off further from the rifling and at 0.045” off and way off loaded at mag length, and repeat some of the testing.

There was no discernible increase in accuracy. But what was missing here was speed! I needed a faster bullet to buck the wind. I an searching for a combination in my rifle to deliver a faster bullet too.

Testing with other powders is needed to fine tune the bullet and barrel combination and that is getting under way. Case in point, I had a bullet from another top manufacturer and was having a tough time getting sub-moa or better groups when I tried a certain powder it was like magic and the bullets grouped extremely well.

 

More to Come!

Selection and Testing of .308 Match Grade Bullets for F-TR Competition By Jason Hale

F-TR Rifle Competition is F-Class Competition where the TR is Target Rifle in .223 or .308 Winchester. At many matches, F-TR competitors are restricted to bi-pod, ruck or sandbags, though at the Nationals a front rest was allowed.

For me and what I’ve studied, its high mass high Ballistic Coefficient (BC) bullets that are most go-to projectiles (bullets).  You still have some folks shooting the 1:12 twist .308 Barrels that shoot between 155 gr and 175 gr projectiles, but mostly the heavy stuff.  Now at this point only one thing matters;

How does it perform with your chosen bullets IN YOUR GUN?  

My recently purchased 28” SS Criterion match barrel doesn’t seem to prefer the heavy 185 gr Berger’s, but I’ve only tried them with Varget, IMR 4064 is another option to try.  I like sticking with Varget since it works so well AND is more forgiving in variable temperatures.

If you’re just getting into competition shooting, you can’t go wrong with the 175 gr Sierra Match Kings.  You can load it to mag length. My factory barrel would shoot ¼” groups all day long.  The only downside is that when the wind is involved, it can get blown around quite a bit more than some of the other more recent slick BC offerings.  I am currently using the Sierra TMK’s and their shooting ½” at 100 yards and have a superior BC to the SMK.  So far I like them, but because the bullet profile is more secant, seating depth may be a hassle during tuning, but it didn’t take too long for me to find a depth that worked well and didn’t compress powder too much.

One item to point out, there is good reason that as a rule of thumb you don’t just try a new projectile which may be the same weight because if you seated them to the same length the depth into the case may change how compressed your charge is.  In addition, there are many other factors that are coming into play.  Spontaneous disassembly (BOOM) of your rifle and perhaps YOU is NOT GOOD.  It is wise to back off by 10% and then work back up while watching for signs of pressure.

Now for the true purpose behind this article, testing your loads.  Finding recommended loads out of a reputable loading manual is your job.  Here I will explain what I see in the data I’ve put together here.

 

The chart below represents testing and data gathered of bullets tested and corresponding results you may find of use.

Good groups 0.5 gr less than SMK due to pressure

 

Nosler 175 Comments/My Approach:

Looking at the Nosler 175 RDF’s you can clearly see that the tip is almost completely closed, which is awesome.  With Nosler’s claimed G7 BC of .270 which beats all of the other 175 gr projectiles, I can’t wait to try this in my current match rig.

Examining previous loads for the 175’s:

My current load for the 175 TMK is 43.0 gr of Varget (0.5 grains less than the SMK) which gets me to approximately 2600 fps.  Surface bearing length differences between the two may be the reasons which pressure signs are reached earlier in the TMK as it has a longer surface bearing length which ads friction.

Comments/Observations the Nosler’s 175 RDF:

One item that catches my attention is the length of the nose profile; it’s very long, which makes sense for a high bc bullet.  This makes it a great option for F-TR type shooters who single load and aren’t bothered by long rounds.  On the flip side, It also makes it difficult to load for magazine length without sacrificing case volume.  I may end up gaining some case volume over some of the other projectiles when loaded to the same length.  If pressures are marginal, I could eek out some addition velocity if accuracy wasn’t sacrificed.  One item examined for overall consistency is measurement of a 10 sample group for Base to Ogive length which can be associated with BC consistency.

 

Noslers numbers were right with the competition, including Berger.  Overall great observations for noslers new RDF.  I will likely start with Varget 8-10% below 43.0 gr and work up from there.  Since my rig is wired up for pressure readings, I’ll have some pressure trends to talk about soon.  I’ll be able to compare them to previous loads that I use as reference (Federal 175 gr Gold Medal Match and Black Hills 175 gr Match).

Comments on the Berger 168 Hybrid Target

There isn’t much to say about Berger other than two words consistency and expensive, or should I perhaps say expensive consistency.  Looking at the data compiled I may be able to drive this bullet to a higher velocity than the heavier 175’s without having to sacrifice anything.  The long nose profile may leave me some extra case capacity and the short bearing length may end up reducing friction from less contact with the bore.  In the end it all comes down to testing; if it doesn’t group, it doesn’t group.  Doing a lot of testing can sometimes be frustrating; but if you enjoy it, don’t give up.  Just don’t waste too much in components trying to get something to shoot.  You’ll know it when you’ve found a forgiving bullet.  This is why the Sierra Match King is still heavily used.  It’s just that easy to tune.  Alas, I am a tinkerer at heart and love a good challenge. I have access to Nosler 175’s for testing so we shall see if my rifle likes them. More later…

Good Shooting!
