I just don’t shoot better with more recoil. I like to use th appropriate bullet on game with the lowest recoil not the highest. That’s where all the manbun stuff comes from.look at the E chart attached above (it's >1,000 ft/lbs of Energy more at the muzzle). Indisputable. And, it's a 6.5 for God's sake (130-160 gr bullets.) We're not talking big boy .338 or DG gun here. They are a PLEASURE to shoot. IF recoil bothers you, get a larger/larger surface area pad, make the gun heavier (Hg reducers, all steel mounts, bipod, full mag/cartridges on sling or stock, quality big scope, etc.) I use a brake on the long range shooters simply to be more accurate (put everything in your/terminal performance favor) for those shots, but it's not absolutely necessary from a felt recoil perspective.
I wouldn’t use a sledgehammer to drive a nail. I would use a hammer.
I shoot all the way up to a 416 Ruger. I don’t think that’s the best gun for deer size game. I don’t shoot it as well as a 223 or 6.5.
I just don’t believe muzzle energy matters that much for the bullets terminal effect on game.
