hopdoc,
The recoil will be alot, but the muzzle break is " sopposed to" reduce recoil by close to 50%. But.... you know I will have to shoot it without the break a few times anyway. Ed says the biggest problem people have with the hot load is the rifle torquing out of your hands because of the rotational force of the 900 grain bullet. I do not know when more of the brass will be coming in. Ed had enough brass in stock to load up 80 rounds for me.
