Time To Begin Reloading

I have been reloading for pistol and rifle cartridges for hunting and target for over 40 years. It is time perhaps to enrich your inner self and reload. It’s fun and saves money too…in the long run.

Browning 7mm Rem Mag -175g Nosler ABLR at 300 and 600yds – Update

My Browning X-Bolt Speed was checked by my son Jason with Nosler 175g ABLR bullets at his F-Class  range at 300 and 600 yards. My scope is the famed Leupold VX-6 3×18 44mm on a 20 MOA Picatinny rail.

X-Bolt Speed

As my readers are aware, I am moose hunting in Newfoundland this September.  Newfoundland’s boreal forest is replete with expansive water soaked bogs and stunted clumps of black spruce known as tuckamores. A great place for moose to thrive, and a tough place to hunt. Distances in these bogs can be as-small-as 100 yards or as far as a 1000 yards or more.

Accordingly, the 300 yd target below shows 2 bullet holes at 11 o’clock at my calculated drop of 3 MOA. Wind was near still so we adjusted 1 MOA for the 6 inch 10 ring and came right 1 MOA. Happy now with the scope at 2 MOA drop at 300 yards with three 10 ring hits and terminal energy is 2578 ft-lbs. Wow!

 

At 600 yards my ballistic data said to shoot at 10.5 MOA drop. Below, the first 2 bullets at 12 and 1 o’clock in the 7 and 8 ring shot 10 inches high, thus we adjusted 2 MOA and shot low at 7 o’clock. We readjusted up 1 MOA and hit the 10 ring at 10 o’clock..

Total actual drop was 9 MOA and not the 10.5 my calculation indicated.

Details matter! Using a laser rangefinder when moose hunting these expansive bogs is a must.

Testing bullets at long range showed that calculated MOA put us on paper but not best for hunting. Making the adjustment on the range just 1.5 MOA up put me in the boiler room at 600 yards. Nice! Energy at 600 yards is in the 1800 ft-lb class. 

UPDATE

My Leupold VX-6 Scope was dialed back to its 100 yard zero, thus I took it back to my range and fired a single 100 yd shot below. Nice!

Good Shooting!

Fathers Day 2023 with my Browning 7mm Rem Mag 26″ X-Bolt and Nosler 175g ABLR

If you didn’t read my last article on this rifle, bullets, powder and primer. Here it is…

Browning X-Bolt Speed 7mm Rem Mag/w Nosler 175g ABLR at Sub-MOA w/ Timney Trigger/Leupold VX-6 – Wow Accuracy at 3000fps

I am very pleased indeed. I was wondering what difference the Norma case makes from new to 5 times shot. So I shot today, between rain drops out of boredom, with a new case, a 3x shot case and a 5 or 6x shot case. The primer went in easy with the 5 or 6x shot  case and harder with the new case. The older case necks were annealed and bullets seated easier than the new case.

I shot the three rounds with 2 old and 1 new case at 150yds. No wind.  The three shot Nosler 175g ABLR group measured 1/2 inch.  MV 3000fps. COL 3.44 inches. See below.

Looks like it makes no difference between new and old cases. I like it!

Good Shooting!

Hornady 7mm 175g ELD-X and Nosler 175g ABLR – 3000fps in Browning Speed 7mm Rem Mag/w Timney Trigger and Leupold Scope

 

Browning X-Bolt Speed SR Bolt Action Centerfire Rifle

Using Alliant RL 22 powder, I have experimented to find my max load and best accuracy for long range moose hunting this fall. At 500 yds I still have 2000 ft-lbs of energy. 

Reloder 22

I found that each bullet type responded well to incremental loadings of Alliant Reloader 22 powder. This powder has been known by some hand loaders, including me, finding lot to lot variation thus load data I worked up is for my rifle and this powder lot only.

My first objective was to be safe and inspect each round before proceeding in incremental increases until either I achieved my velocity/energy goal or ran into case/primer concerns. I was able to achieve just over 3000 fps with nary an issue, even with a 9.5 barrel twist. 

My COAL objective was to set it at 20 thousandths less than the rifle lands and chronograph each bullet, then shoot for 3 shot groups at 100 yards. .On  the first pass, I achieved a 7/8 inch group at 100 yards with outside temp around 70 degrees and a cold barrel.

My Timney trigger was set a 3 pounds and worked crisply. Thanks Timney!

 

 

 

 

 

 

My Leupold VX-6 3-18 was set at 10x. Love my Leupold!

Leupold VX-6 CDS Rifle Scope - 307376, Rifle Scopes and Accessories at ...

I believe 3 shot bench groups are all that is necessary for hunting accuracy.  It is very rare to fire more than 3 rounds at one big game animal. My confidence is very high with this Browning in hand. Next is to shoot off hand and with a tripod type rest and shoot a fast follow up shot with the short 60 degree bolt throw.

Good Shooting!

 

Browning X-Bolt Speed and Cartridge Overall Length Surprise

Hand-loaders love to experiment with bullet seating depth to increase accuracy.  In a new rifle, I sometimes discover that the magazine length or clip is the limiting factor for OAL and not the bullet distance to the rifling. This can be disappointing as it limits bullet OAL and can affect best accuracy. 

Pleasantly, I have been surprised to find the clip length for my Browning 7mm Rem Mag is 3.57 inches.

X-Bolt Rotary Magazine – Burnt Bronze Cerakote

 

SAAMI lists the max overall cartridge length OAL at 3.29 inches for off the shelf ammo. The chamber and magazine in my Browning allows me to hand-load longer than published OAL, thus leaving room for accuracy experimentation we hand-loader often do.

The caveat here is that the bullet must contact the case neck at least to bullet diameter. In my case that length is .284 inches. 

OAL can vary from spitzer to round nose.  I measure max OAL for each cartridge and bullet and subtract 20 thousandths (give or take) for spitzers and 50 thou or more for round nose.

Experimentation will tell where your best accuracy is.

I find that in my 7 MM Rem Mag, I’m not be limited by SAAMI OAL of 3.29 inches. I can use OAL’s out to 3.4 inches with my Nosler 175 g ABLR. Very nice indeed!!

Good Shooting!

Reloading and Shooting 7mm RM 175g ABLR 150yd Sub MOA Max Load

Reloading and Shooting Thoughts for Long Range Hunting.

It is important to recognize that there are significant differences from hunting vs target reloading/shooting.

Hunters want a light rifle, (6 to 9 pounds) that shoots accurately out of a cold barrel.

It is the first cold barrel shot that really counts to anchor your big game, not the second, third or fourth shot.

Sure, a follow up shot is also important in the case that your game is still on its feet, but that first cold barrel shot is key.

Shoot for 3 shot groups not 5 shot groups.

Below from my new Browning X-Bolt Speed 7mm Rem Mag  at 150 yards at 7/8 inch group at 3000fps. I will practice out to 600 yards.

Nosler 175g ABLR 3 shot
group RL 22 at 150 yds 2975 fps
7/8 inch

Target shooters on the other hand want a heavy rifle and  heavy barreled rifle (often well over 10 to 20 pounds to absorb heat from the barrel and reduce felt recoil. Best target groups are from a warmer barrel not a cold barrel. And the bullet is chambered to engage the rifling thus increasing chamber pressure.  

Hunter’s who reload, prefer to reload to around 15 to 30 thousandths off the rifling lands and often can shoot a hotter and faster bullet to maintain more delivered energy to big game. My 7mm Rem Mag Browning X-Bolt delivers 2000 ft-lbs. of energy at 550 yards. 

By reloading for your hunting rifle, you can customize case, powder, bullet and primer, save cost, get more satisfaction,  while increasing long range accuracy from a cold barrel.

Since preparing to hunt moose this fall, at long range, I pay more attention to case concentricity, seating depth and neck tension. It has helped greatly.

l_749007305_1.jpg

One final thought, I swab the bore at the end of cleaning with a degreaser solvent to remove any lubricant or cleaning agent to improve the first cold shot.

It works great!

Good Hunting!

Redding Competition Bushing Neck Sizer Die for 7mm Rem Mag

For Long range shooting I need consistent neck tension on my bottleneck bullets. I ordered this Redding Bushing Neck sizer die from Midway for $148 dollars and a Titanium Nitride Bushing $34 below for my 7mm Rem Mag.

Do you need this special neck sizer for hunting here in New England? Not really, unless you shoot beyond 200 yards or are strong on the details side of things. 

Redding Competition Bushing Neck Sizer Die

Below: Titanium Nitride Bushing

Redding Neck Sizer Die Bushing

Reading the instructions, I had to unscrew the micrometer and spring/shaft portion from the body and place the bushing into the main body tube where the micrometer came out.

This die comes with a primer-remover-shaft that allows you to use the primer remover, or not, by adjusting the shaft in or out. I did not want to de-prime, as my brass was full length sized, confirmed concentric to 0.003″ or less on my Sinclair gage, and then primed.

My already loaded rounds measure 0.311″ Outside Diameter.  My neck bushing has a 0.309″ opening will now size the empty primed and full length brass to 0.309″ to grip the bullet by 0.002″ tension.

Here is a photo and Stat’s of the latest Nosler 175g ABLR 3 shot Nosler 175g ABLR 3 shot 7/8″ group RL 22 at 150 yds.

 

Stats – Average 2964.82 fps
Stats – Highest 2975.04 fps
Stats – Lowest 2953.98 fps
Stats – Ext. Spread 21.06 fps
Stats – Std. Dev 10.55 fps

Primers and case look normal. I could punch the 3000fps mark but with this really tight 150 yard 7/8″group, I am very happy here with an SD of 10.

Good Shooting!

Nosler AccuBond Long Range for 7mm Rem Mag

I have been a Nosler fan since my African Safari some years back and have taken two bull moose and whitetails with AccuBonds from 140 grain up to 300 grains with great success on big game.

Accordingly, I have written extensively about Nosler bullets in my New Hampshire Rifleman Magazine using AccuBonds, Partitions as well as E-Tips. All world class hunting bullets that hit hard, stay together and penetrate deep. Handloading my own bullets are key to my satisfaction and success.

The AccuBond Long Range ABLR bullet is in a class all by itself, providing very low drag, a bonded bullet that can mushroom as low as 1350 fps and stays together up to 3000 fps. No other bullet can make that claim.

https://www.nosler.com/products/bullets/product-line/accubondr-long-range.html

 

The ABLR is offered in 150g, 168g, and 175g bullets for those who may encounter long range shots. In my case, I will be hunting Newfoundland Moose among the myriad of bogs that can span many hundreds of yards.

Below is the Trajectory Chart and Delivered Energy. See the 500 Yd data in bold for 2100 ft-lbs delivered energy.

Browning X-Bolt Speed- Testing with Vihtavuori N560 Smokeless Gun Powder and Nosler 175g ABLR’s-Updated

In prep for my 7mm Rem Mag cartridge custom loads and my fall Newfoundland Moose hunt I had some difficulty getting Reloader 22 powder for reloading my 7mm Rem Mag.

Accordingly, I purchased some available Vihta. N560 Powder that Nosler had listed for 7mm Rem Mag with Nosler 175 grain ABLR’s with a 24 inch barrel and 9 twist.

Vihtavuori N560 1 Pound of Smokeless Powder

Its burn rate is near to RL 22. My rifle is a 26 inch barrel and 9.5 twist. Subtle differences in length and twist can shift ideal powder burn rate preferences to one side or another. You just have to find the sweet spot and the powder. 

Early N560 Powder results showed extreme spread (ES) and standard deviation (SD), at lower velocities, were excellent, thus I continued working up the load. 

Many handloaders have found that some rifles with 9.5 twist rates do not like the 175 grain bullets’ accuracy but so far my rifle likes them with this N560 powder.

As those who experiment with loads are aware, powder, can and does vary from lot-to-lot, thus backing off to starting loads and working up slowly is best. Observing the cartridge case and resulting primer can tell quite a bit as you approach a max load. As you incrementally approach hotter loads, the primer will begin to flatten into a pancake.

I try to avoid what some call “sticky bolt”, a term for supposedly “manageable” over pressure. So far so good.

As I load each round, I use a sharpie pen to write the powder name, grains, and bullet type/weight used on the brass.

I have achieved the near to 3000 fps under preliminary testing at an outside temperature of 45ºF and cartridge and primers look flatter but normal. First 3 shot group was just 1.0 inches at 100 yards. 

Next is to check for Extreme Spread and Standard Deviation below with Labradar data.

JBM Ballistic Data indicates 1891 ft-lbs delivered at 600 Yards, 10 mph crosswind moves the bullet 17 inches left or right. At 500 yds delivers 2100 ft-lbs and 11 inch crosswind. At 400 yds delivers 2330 ft-lbs and 7 inch crosswind.

Next is to practice at those distances and collect real field data to see what limitations surface. More to come!

Good Hunting!

Cartridge Reloading Gives Me More Shooting and Hunting Satisfaction

When store shelves are bare of your favorite rifle cartridge and bullet, I just reach into my reloading cupboard and load some up and go hunt or shoot.

Yes, sometime I run out of something but more than not, I have it before the big stores have your pet load.

Beyond that, my cartridges are customized to my rifle thus increasing accuracy. 

A sense of accomplishment? You bet!

Many years ago I purchased an RCBS Reloading press and never looked back. Reloading your own cartridges are a cost effective solution too, if you shoot regularly. I load pistol cartridges too.  

There are other reloading press companies and beginner kits out there to get you started.

RCBS offers the Explorer Reloading Kit for just $339.99.
