You guys wanna run your rigs at velocities and pressures above sammi specs. go for it, but don't try and convince everyone that it's acceptable. There have been a number of cases where guns have blown up and the cause was an overcharge of powder. Your justification that it hasn't happened to yo yet doesn't mean it won't. I've personally seen a bolt with cracked lugs from overloading. Luckily caught before somebody had a big accident.

Sounds like you would be the firt guy to tell P.O. Ackley he did not know what he was doing. Ever wonder why gun makers have not chambered rifles in Ackley chambers? SAAMI is the answer to that question. I wonder how many hudreds of thousands of actions have an Ackley chamber on them, that shoot over SAAMI spec pressures for the parent cartridge.
No one knows of actions that have blown up with the exception of substitution of the wrong powder that I have first hand knowledge of.
You guys that do not like wild cats, I take it that the only reason that you visit the "Wild Cat" section on this board is argue with people?
