Re: Browning Abolt for long range rifle?

if you have tried to get the BOSS tuned in and still haven't gotten it to shoot well , I would look at having it bedded , the barrel free floated and the trigger worked. If it shoots good one day and not the next then its likly having to do with some sort of bedding contact issues.

I personaly would have the boss taken off and have a good brake installed if you feel the need for a brake.

But the A-Bolt action is as good as any to build on as long as the job is done right and a good barrel is installed.

But first , assuming you have a good scope , check all the scope mounting hardwear make sure that its all tight and the scope is not in a bind , then bed the rifle and relieve the barrel is not touching the stock. After all this is done and everthing has checked out ok pick a bullet you want to shoot and get a load for it where its about the velocity you want then try to dial the barrel in again. The BOSS system causes a major pain for the reloader because it is desgined to tune the gun to the load where in reloading your trying to tune the load to the gun , if you try to many loads and try to tune each one you end up chasing your taill till the barrel is shot out!!

Re: Browning Abolt for long range rifle?

Thanks you for all the good input to the problem.

Magman thanks for the link to Jon A's rifle. Looks like he lives close to my next of the wood in the N.W. His rifle is exactly what I had in mind for my build.

JDJONES thanks I think the Boss sucks and I have been doing exactly that.(chasen my tail)

Re: Browning Abolt for long range rifle?

I have to disagree with removing the Boss. I have two A-Bolt rifles with the Boss. Both work as advertised. My .300 Winchester will shoot most any 180 gr. bullet into 1/2 inch at 100 yds. (including several factory loads). I have been working with the 185 Berger VLD and 3-shot groups are averaging around 1/4" at 100 yds. I have a load for the 165 Hornady SST that shoots around .150 average for 3-shots. I have taken an antelope at 483 yds. with the Hornady. Both the Berger and Hornady are seated to touch the lands so they are too long for the magazine. I shoot 2 shot groups until I get both bullets to go thru the same hole. I can adjust to a new bullet weight with 10 bullets. I just shot a test with the Sierra 200 gr. Game King seated deep to magazine depth (I have to get a .375 Magnum clip to allow longer OAL.) The two shot groups ranged from .937 with #3.5 to .067 and .254 with a 2.7 setting. My 22-250 has shot several groups at 200 yds. that were under 1/4".

I did modify my rifle to fully free float the barrel. It is the synthetic stock S/S Stalker model. I also relieved the forend tip under the barrel quite a bit. Before I did this work it was inconsistant. One day grouping good but the next it was over 1 1/2" at 100 yds. Relieving the stock under the barrel at the forend tip is critical. I believe that the barrel is flexing and hitting the stock during recoil. I have done most of my shooting with the CR device. I have switched back to the Boss and found that it really does reduce recoil and barrel rise.

Re: Browning Abolt for long range rifle?

I have got the same thing with a wood stock, it has a Vari-x 2 3-9 power. I couldn't shoot it without flinching with the factory recoil pad, so I bought a Limbsaver and WOW. Good fit and made a world of difference. I can shoot 210 Barnes XLC bullets with 78 gr RL22 @ 2890FPS and they don't hurt. I personally have to shoot 4-5 rounds through it before I begin to settle down and I actually become more accurate the more I shoot it...to a point. No BOSS but I am thinking about a Muzzle Brake to tame it a little more but I have a Mercury Tube that I am going to install this winter to see how it helps.

Sorry I haven't sat down and done a real range test but it is winter and I will have nothing to do....

Re: Browning Abolt for long range rifle?

As folks are saying, the Browning is more than capable to shoot 600-700 yards, but the trick being to co-ordinate tuning the BOSS with your loads. I have put MANY bullets down the barrel of my 300 Winchester Magnum S/S to try to find the secret behind it.

When I talked with Browning they told me that adjusting the BOSS is a slow process where a 1/4 turn change can send you past the sweet spot and open your groups back up as much as an inch.

Building the sweetspot charts is an exhaustive process where they increment the BOSS by a single sitting, per group. Their advise was to select the setting of a round that was closest to what I wanted to shoot, and use that as a starting point. After putting more than 500 rounds through mine "chasing my tail" that turned out to be the best advise. Mine now shoots 1/2 MOA and that's good enough for this rifle.

BTW I also used QUICKLOAD to help determine the correct powder/bullet combo to use.
