We can't use centerfire to hunt deer, shotguns or bows. But they found a way around it with the straight walled 450 bushmaster. I want one. Probably the new Ruger camo in 22" I noticed they all come with muzzle brakes. I can't stand muzzle brakes because they make a loud gun even louder. I've never shot a bolt 450 BM but from what I have read on some forums is they kick a ton and need a brake. I dunno if people are getting soft or what but I was shooting 12 gauge at age 10 and never have a brake on it. Never had one on any shotgun. Is it really needed? Also 16" vs 22" barrel what are the pros and cons of each in the BM?
