Browning had a contest a while back to test the BOSS system. The fellow that won shot under 1/4" group at 100m using his handloads, the BOSS system, and aBrowning A-Bolt .243 Win. or.223 Rem. I would not mind owning a rifle with the BOSS system. Good luck.

I own one on my A-Bolt .270wsm. I really like it, I wear hearing protection all the time so the sound doesnt bother me but having almost no kick is great. I can shoot it all day long and not feel it. My buddy has a A-bolt .270 without a boss and we compared the two and its night and day. But if you do your own loading you dont really need it but I dont so boss is even better for me.
Shot the group below with a browning 7mm with boss,have sold the rifle since so don't remember the setting but the group was with factory 162 gr bullets.
Had a browning 300wsm with boss and it shot very well too but both took awhile to find the right settings for reloads,because I do reload is why I sold them both.
Buddy, it's always wise to use ear pertection, but if you don't it can blow adrum. I shot the .338 A-bolt w/Bossbetween two boulders in CO. and I thought I had blown one for sure!
