I posted a comment about fire forming in the garage. I thought of my now deceased good buddy who had a 1950’s era technique for finding a max load. Increase powder until a primer blows or falls out then decrease by 1/2 grain.
He was one of the guys who added sand to cream of wheat to more fully form cases.
He got a chronograph and developed a new technique. He loved numbers and decided a 22” barreled 270W should move a 130 partition along at a minimum of 3200 so he added powder until he got that velocity. Then he shot 3 or 4 rounds and if the primers didn’t fall out he was good to go.
Really great guy who was loads of fun. But one day he asked my why I always stood behind him slightly to his left, he was right handed. I explained that I wanted his thick skull between me and his rifle’s receiver. He said I was a pussy.
