Re: 300 win mag muzzel break or no break
My first built 300wm, had a Holland brake, it only added 1.25" to the stick. When I rebarreled it at 5440 rds I went back with another Holland. Shot lots of others along the way, nothing came close to the Holland. Getting one for the .308win, this one will be from Liberty Suppressor's, (David's own design) as will the next 300wm brake.
Cans are nice, but not near as effective(recoil) as a brake, and that is fact. Besides, shoot a comp. with a can, where a can cover is not allowed, and see how long before you start thinking brake. Everyone whines about brakes, until they have shot one. If it's real, a can is the only way to dance, if just playing, screw the brake on and don't look back. YMMV
