Had one on a Browning A-bolt .338 Win Mag that came with a Boss sytem on it. Hated that break. Gun was nice, but the brake was only a headache to me. Would never have one again.
Too loud( sets off car alarms at the range!) Blows dust in your face when you shoot prone with a bipod and just looks ugly!!!
If I wanted a recoil reduction, I'd choose a top of the line recoil pad and also a mercury or spring reducer installed in the stock.
Just for FYI purposes. I asked Santa for a Caldwell Lead Sled for Xmas. He got me one. I added two 25lbs bags of shot to it and shot my 12 ga with slugs and my .338 Win Mag with 225grain pills off of the bench. Never even noticed the recoil!!!! Reduced by a significant margin! Makes all day sessions at the range with bigger guns a breeze. Now, you can sight in at 100 yds with any gun or load and play until your guns' doing exactly what you want it to. Then, when you hunt, one or two shots at an animal will
nevereven phaseyou.
Good luck!
