So far, in the the old simulator program that I lost in that computer crash, I was using the theoretical default value for the gross capacity of the .220 Howell design � 62 grains of water, IIRC.
I wonder what it'd be for well made cases, either those made on special contract or those converted from good .25-06 brass.
It's one of the most crucial of fundamental first givens for interior-ballistics calculations.
As soon as I get my bank balance back up to squat, I'll order a replacement (current version) of that old lost program. But I'll still wonder what value to use for the average gross capacity.
"Good enough" isn't.
Always take your responsibilities seriously but never yourself.
