OP is going to shoot Suppressed, no brake.I've built a number of 8-10 lb 338 RUMs and they really are a pleasure to shoot with a quality brake and a 250 hr bullet, all 1000+ yard guns with ease. They don't need to be as heavy as guys think but you do have to choose wisely.
I know, addressed that, there is little difference when you choose the right suppressor, you gain a little recoil but not significant.OP is going to shoot Suppressed, no brake.
I ordered a Thunderbeast suppressor for mine. I have the brake on it until the suppressor arrives. I feel like it will reduce recoil as much as the brake.
