•Browning A-Bolt II Stainless Stalker 280 Remington, Lefthanded B.O.S.S. Handloaded 120 grain Barnes TTSX, 0.324" 3-Shots at 100m (110y) •Browning A-Bolt II Stainless Stalker 7RM, Lefthanded B.O.S.S. Factory Barnes Ammo 140 grain TTSX, 0.622" 3-Shots at 100m (110y) Amazing rifles and both have good glass on them. The 280 Rem wears a Bushnell 6500 2.5-16x50mm Mil-Dot and the 7RM wears a Bushnell LRHSi 4.5-18x44mm G2 illuminated FFP. Excellent low light scopes for Alberta, Canada whitetails and the LRHSi is a superior scope to many European big name scopes I've owned and the turret adjustments are as good as any out there.

Hey Brother ,I'm a lefty and been shooting a Boss BAR 30/06 for many years. Browning sent me the extra sleeve on request for free. Many deer and several large black bears have fallen to it. My son took his first two bears with it. Browning firearms overall are hard to beat. Also shoot a LH A-bolt st. stalker in '06. Great guns. I appreciate your informed content and responses.

I agree Paul, Browning Bar is a grat deal for a very good Semi-Auto that is as accurate as most Bolt Action guns... I have been thinking of buying an X-Bolt maybe will look into that again... Thanks for letting me know and good hunting. Joseph

I bought a used A-Bolt 270 with Boss, amazing shooter also, will have got it down to less than 1/2 inch 3 shot group after some tunning, I too pictures no videos... will have to do a video soon... I am looking for 260 Rem or 6.5 CM now :)

Finally ordered my dream rifle and it has the BOSS system. How many rounds did your spend getting it tuned? 300 WSM is a pain to find and I don't want to waste it. (Any tips would be greatly appreciated.)

[@shootinglefthanded9887]

Hi Robert, I suggest following the video on the Browning Website. It was quick, less than 10 rounds, and just find a cheap box to brakeit into to buildup some cover in the barrell

I have a A-Bolt -II with the boss. It is chambered for .308 Win. I get 3/8"-1/2" groups at 100 yards.

Browning always good bet

Boss will cut recoil,,boss adjustment will move poi ,,,will it improve groups? Could not prove that by me!

[@shootinglefthanded9887]

Hello Michael, the Boss does change the frequency of the of the barrel, this changes when the bullet exits the barrel... if you imagen the behavior of the barrel as a sin wave at the very top and very bottom of the wave form there is little elevation change where at the slope sides the elevation change is so fast... by controlling the the time of when the bullet exit the barrel this provide less deviation relevant to the speed of the bullet... Same as hand loading with different speed... handloading we adjust the speed of the bullet that it exits when the barrel at that silent time at the very top of the wave form or bottom... just a simple explanation, there is much more to it...

[@jonkuemmerlein639]

You're not letting the barrel cool. You're going all over the paper, plus the BOSS should be tightened with the wrench, to make it tight!

[@shootinglefthanded9887]

Thanks Jon for feedback, the time between shots is about 3 to 5 minutes, I have cut the video short... I kept adjusting and waiting for the barrel to cool down... here is a better video of load development kzbin.info/www/bejne/maCZeWykbc6BfMU&ab_channel=ShootingLeftHanded

Does it make it louder

[@shootinglefthanded9887]

Hello Edie, the BAR has two options if not mistaken, Flash Hider and Muzzle Brake... the one I have is with the Muzzle Brake which will always make the gun louder to the sides of the gun as it vents the gases to the sides as the bullet is exiting the barrel... the Flash Hider will not change the sound profile that much... note that both BOSS' don't add to the volume over all they just change direction of the sound... Hope this helps

@@shootinglefthanded9887 thanks I have a Browning A Bolt in 300 win mag would love to make it louder lol I just like big bangs

[@shootinglefthanded9887]

@@watcher6068 If your rifle is threaded, you can add muzzle brake to it if not you can have it threaded and add muzzle brake... :) people normally want to make their guns quite so they don't bother people or animals around them... also to protect the their hearing...
