Shooting a RUM without a brake.
I do not have a brake on my 300 Ultra. I use a slip on recoil pad which works fine for me. The first shot always seems to give me a pretty good jolt and then after that it's no big thing... weird. With the slip-on I can shoot it from the bench all day with absolutley no soreness. The other day I forgot my slip-on pad and fired it with just a Carhart coat. I thought I was going to get punished but it felt just as if I were wearing the slip-on, And after shooting the Ultra, I shot the 300 WSM
which seemed like a 243.
A couple of tips. Make sure the butt of the rifle is snug and firm in the pocket of your shoulder, not out on the ball. That makes a real big difference. Another thing, develop a shooting position on the bench that does not have you leaning into the rifle too much. The more errect your position to the rifle, the less the recoil will affect you. Technique is a BIG part of the game.
