@ Rocky Mtn,
Brakes weren't around, in those days, although Muzzle "venting" was just starting up, I have never cared for, the "Blast" coming out of, either the vents or, Brakes, even tho wearing Ear Plugs. I did think about a Brake for my New .243 Win. Tikka T3, but got to thinking IF, I ever forgot, to put my Plugs "IN", I'd be "Toast", hearing wise! My Custom .338 W Mag. Wby MK V action, with, 25 1/2" Douglas premium Bbl. is long gone, replaced by, a 7 mm Rem Mag. M-700 26" bbl. @ 8.5 Pounds, that got replaced by, a 7.5 Pound, 24 inch, SS Tikka T3, Lite, in .270 WSM that, I can carry everywhere, for miles and miles and I can shoot, a lot in practice and have FUN, due to, LOW recoil,. It's gonna be, my last Elk Rifle as, I'm very happy with it ! The 140 AccuBond @ 3,150 FPS and still going, OVER 2,000 FPS at 750 Yards, I'm, "good" for where/ how, I "Hunt" !
