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

The Browning X-Bolt Speed 7mm Rem Mag 26 inch 9.5 twist barrel I have tested this past three months with a new Timney trigger (set at 3 lbs), simply put a wide smile on my face today. 

X-Bolt Speed

Some shooters say 7mm Rem Mag in 9.5 twist is said to rarely achieve 175g spitzers at 3000fps and MOA accuracy. This may be true for some, but not here.

I am here to tell you that I have achieved hand-loaded sub-MOA results with Nosler 175g ABLR and other bullet manufacturers to 3000 fps.

Using Alliant RL 22 or Vihtavuori N560 Smokeless Gun Powder have both pushed Nosler 175 ABLR to 3000 fps while achieving sub-MOA 3 shot 100 yd accuracy. . Standard Deviation hovers around 10 fps. I am using Norma Cases and CCI or Winchester Mag primers.

I have achieved the bench rest group below three times in a row today. It’s no fluke!

I attribute my success with attention to handloading detail, a great Browning rifle, a Leupold scope, a Timney Trigger, Nosler bullets and world class powders. Note: 7mm Rem Mag ammo is on the shelf across the world for hunters.

Good Shooting!

Muzzleloader Bullet Thoughts

I ran into a friend who shot a doe with spitzer type muzzleloader bullet. The deer ran hundreds of yards before dropping. And he recovered the bullet, which never mushroomed to deliver killing energy.

I advocate for semi-spitzers with rounded nose, round/flat nose or hollow point bullets for muzzleloaders that deliver sufficient energy to open/ mushroom the bullet. 

Do your homework and read up.

Avoid spitzer styles that are difficult to open and mushroom.

Most shots are taken at 40 to 60 yards and do not need sharply pointed bullets. 

You will be glad you changed bullets. I like a 300 grain semi-spitzer/hollow point for my 50 cal.  and at least 100 grains of pyrodex. 

Some examples of better mushrooming bullets.

Now is the time to shop!

I avoid sharp sleek pointed bullets that are not designed to readily expand. 

Good Shooting!

 

 

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!

Reloading: Cartridge and Bullet Concentricity Tests for Hunting

 If you hunt and shoot beyond 200 yards, bullet and brass concentricity (wabble) can matter. Experienced long range shooters call it “runout.” I have shot at 600 yards at targets on occasion but rarely checked for concentricity/runout till prepping for this falls moose hunt. 

Accordingly, I just purchased a Sinclair Concentricity gage to check for runout and to see groups improve. The idea is to eliminate fliers! But that required me to do more brass case prep too. That must have helped as well. Some swear by it, some don’t.

l_749007305_1.jpg

First tests were for the case neck on those I had already full length resized a week earlier.

 

After checking 30 cases, half were at .003″ or greater runout (wobble), half were less.  Some long range hand loaders suggest that 0.003″ is the max runout.

What to do?

I ran these .003 cases back through my full length sizing die a few times, rotating 90 degrees and retested. Runout (wobble) improved to .0015″ or less.

Next is to load some bullets and retest for bullet runout.

All bullet retests for runout were 0.003″ or less. Nice!

Doing this test suggests that the bullet is better aligned to enter the rifling nearer to parallel. So lets see some targets…

Below this Nosler 168g ABLR group shrunk from 2 inches to 1 1/8 inch group at 150 yards  is an example of what the Sinclair Concentricity Gage did for me.  Sub-MOA groups below!

 

The next picture below is of the same 168g ABLR bullet at 150 yd distance but the OAL was longer (0.020 off the lands).

The 1/4 inch difference in grouping photos was probably me. But you can see these are both sub-moa groups.

Lesson learned! To establish a best in class reloading process with or without the gage.

Good Shooting!

Reloaders- Smokeless Powder Burn Rate Charts Aid in Alternatives

Not finding your favorite powder for sale?  This chart can help find powders closest to yours. I did that with my alternative to Reloader 22 and found Viht N560 and it worked great. Nosler listed it in their manual. 

Reloading safety is of prime importance thus you must begin a new powder at starting loads and work up. The internet should give some start load data sources if you search your caliber and alternative powders.

All reloading manuals list alternative powders but there are some older reloading manuals that are not current in new state-of-the-art powders. 

IMR published a burn rate chart PDF below and includes many brands.

Check it out.

Adding a Timney Trigger to my Browning X-Bolt Speed

Removing the two mounting bolts, you can pop out the barrel and action with some finagling and prying. It is a tight fit. 

Here is the Timney Trigger below.

Below there are 2 pins that hold the trigger in the half moon cutouts in the barrel. Use a 1/16 punch to remove the two pins and the trigger will come off. 

The part I did not expect is that the Timney did not just drop in. The forward slot was too narrow to fit in the half moon cutout. I had to grind off a few thousandths from the trigger housing to widen the slot with a Dremel tool. 

Below you can see my Dremel tool that I used to grind the forward pin housing a bit. Took me 20 minutes to grind and fit it. Not overly hard with the right tool. Some triggers drop in to those slots in videos. 

Below is the Timney trigger installed. The whole process took me about an hour or less.

I put my Lyman Trigger test gauge on the Timney and as expected it measured 3 pounds almost. Two pounds fifteen point nine ounces. I tested again at 3 pounds exact. Test the safety slide to be sure it works. Mounting bolts need torque to 35 inch-lbs.

Below is a video that helped me.

 

Good Shooting.

Basic Rifle Cartridge Reloading Dies

Decades ago, I started out by shooting a few boxes of .270 Winchester ammo and kept the brass. This once fired ammo case is a great start to reload. But you need dies to reform brass, add a primer, powder and press the bullet.

For me, reloading is the ultimate satisfaction of doing-it-yourself like DIY.

Like chipping a broadhead from a piece of stone and killing game by your own hand as our ancestors did is the ultimate in satisfaction. 

The component of a cartridge requires a brass case to hold the powder, primer and bullet.

The brass needs to be “resized” in reloading dies, spent primer removed and replaced (left die) and a bullet seating die (right).

Full-Length Die Set - Group A - Popular Rifle Cartridges

 But new brass can be purchased too. See image below.

A reloading press and dies are essential. There are several companies who cater to reloaders.

A basic bottle-neck die set consists of two dies, one to resize the case and another to press the bullet into the case. See Photo above.

Every cartridge caliber needs its own die set. Die set costs to load for hunting typically cost less than $70.00 for a set.

Reloading for long distance hunting and shooting can be more exacting and cost much more. Like this Redding Die Set with micrometer bullet seating.

Redding Premium Series Die Sets

 

I had my first Savage .270 Winchester and loaded it with an RCBS Press and dies 40 years ago.  I use it to this day and saved untold dollars and Did-It-Myself…to my great satisfaction. I hunted Africa with my custom loads.

The key to good reloading technique is to read reloading manuals and guides, watch reloading video’s on you-tube. Listen and pay attention to areas of safety. Inspect your brass and spent primers for gas leaks, case damage of older brass. RCBS offers a free downloadable reloading guide.

https://www.rcbs.com/rcbs-downloadable-guide.html

Companies like Nosler, Hornady, Speer, Lyman, and several others sell reloading manuals. My two favorite manuals are Nosler and Hornady. Don’t forget all the videos on the web.

Smokeless Gunpowder Shelf Life

Recently, I hand-loaded some Alliant Reloader Powder I had in my lower cool dry garage cupboard.

Reloder 19

It was for my 7mm Rem Mag rifle and discovered the powder lost some of its potency. It was an opened can and had about a half pound left. All of the loaded ammo fired fine but lost a couple hundred feet-per-second from published data. This powder had very little solvent smell and looked fine.

I was looking for a near max load.

I loaded rounds later in steps to see what I could wring out and did so just fine.

I would buy a new pound of Alliant Powder as soon as it is available and consider quickly using the older powder. 

I also loaded some rounds with a new can of IMR powder which had a potent solvent smell. These rounds followed published data very well. 

New powders often have a solvent Acetone like smell and over time the opened can will lose the solvent smell. Over longer periods, it will degrade to an acidic off smell.  When powder has that off smell it is time to dispose of the powder. Below is what Alliant says about storage and handling of modern powder.

Browning X-Bolt Factory Trigger Adjustment?

First, I like my new Browning X-Bolt rifle, but some of you know I had difficulty cleaning the red sealant out of the adjustment screw Allen wrench hole a few weeks back. Thinking my 2mm wrench stripped the hole. But I revisited the adjustment with a tool that I can put pressure on to get deeper in the Allen socket hole.

 

And it worked. The screw turned.

Thinking, now I can adjust it down to 3 pounds, but the adjustment screw did not lower the trigger to 3 pounds in fact just an ounce below 4 pounds, no matter what I did. And I am pretty good with tools!

Accordingly, frustrated I reassembled the trigger base and shot some snap caps for how the trigger felt. Nope, not much change. They say you can buy an adjustment spring and replace the existing trigger spring but it is not an easy job.

For me, I will test a Timney trigger when it arrives. It will adjust 1.5 to 4 lbs. Mine will be set at the factory to 3 pounds.

The only downside is that it costs around $200.00 and you have to take the stock off, remove and replace the trigger and proof the safety latch works. The Timney will no longer lock the bolt however. Many shooters see this as a minor loss.

Shooting a scoped semi-auto .308 or 6.5 Creed AR for Hunting?

Shooting a semi-auto .308 or 6.5 Creedmoor AR for hunting can be done and done well. An AR example below. I prefer a bolt action but hey…this works. A great wild boar rifle too, where southern and western farmers are overrun with them.

Savage Arms MSR10 Hunter Overwatch 6.5 Crd Semi-Automatic AR-10 Rifle, Matte Camo - 22994

 

The semi-auto AR 10 platform for hunting is a do-it-all rifle for protection, hunting game, and predators.

I personally prefer a bolt action rifle but in the right hands, this rifle works. In brown bear country, this reliable rifle gives comfort to folks living off-grid as does a 44 mag pistol as a side arm.

Ranchers use this tool like they use a hammer. If you have a nail, then the hammer is the right tool. If you have a brown bear sniffing in your direction, having a large clip of .308 cartridges at the ready can be comforting. Or live in Texas or Florida where they are overrun with pigs.

I am no expert on AR Rifles for hunting big game but I did find a great article on the web by Outdoor Life.
