See, this is what confuses me, the manuals show .357 mag pressures at 30-40K psi, and 40 cal in the same arena. The little book that came with the hardness tester shows a 10.1 bhn should have a max pressure of 12895, fine for most 38 and 45 loads, but nowhere close to the pressures of 40 cal.
What am I overlooking?
Thanks, Steve W.
