Don't do it. It does cause wear and damage. If you really want to do it, get a Ruger and have a gunsmith replace the internals. The action needs to be hardened, geometry angles need to be modified and everything needs to be polished. When you do it, budget for a rebuild also. Slip hammering is not damaging in itself. There are just a few things that can get out of alignment and tolerancs that will change enough to batter the hand and possibly break the bolt if you speed things up. I have broken a few parts and spent some money myself. It is fun and even fastdraw and sliphammering is fun. No, I can't shoot aspirin out of the sky. I have shot in fastdraw, CAS and even exhibition gunfight reenactments. I did break internals, often.
