I recently purchased a Browning Bar Safari Grade, 300 WSM with the BOSS system. Now I' ll be first to admit that I didn' t believe all the hype about the BOSS system but wanted a BAR in 300 WSM and the gun shop only had one with the BOSS system so I bought it. This past weekend I put the gun in a rest (Outers - the blue one) on a bench and checked its accuracy.
To all those bolt action guys that always say an auto loader isn' t as accurate as a bolt...I say PPphhhhhhhtttttt.[:-] After I zero' d the scope and the BOSS system, I shot
two three shot, one hole groups you can cover with a dime.

I was using Winchester Ballistic Silvertips in 150 grain. I' m also using a Nikon Monarch 3 X 12 scope. Even I was amazed after I shot the first group, so I tried it again and WOW, what a gun, what a cartridge! This was accomplished at 100 yards. Now if I can only take a bench, the gun rest, and get my quarry to stand still for say about 5 minutes....I' ll never miss[

At least now I know the set up is accurate enough, the rest is up to me!
