Gary, staying under some velocity doesn't have anything to do with low pressure or any pressure. I've reloaded shells at 1300fps at around 7000psi. They were only 3/4oz, but that's one of the reasons I could. A quick look at a reloading hand book I see from 5500psi to 10,300psi with a 1oz load at 1200fps. So please don't assume some velocity assures a safe pressure. What I think most of us worry about is cracking the wood or getting the barrels sloppy on the receiver from repeated use of high pressure factory ammo.
