Chambering, bullet, velocity, bbl length, charge weight, might be informative.
Oh, and the pressure you generated, since that's a big thing with you. And how you calc'd it.
I don't think that there is really such a thing as "calculating" pressure. I also don't beleive there is such a thing as free lunch. But If I use the same components in the same length barrel and get the same velocity as is listed in the factory pressure tested data, I think I'm probably within safe pressures. I don't like exceeding the powder charges listed by the manufacturers and manuals............................DJ
