Cpttango. Thanks for the last statement. I think I understand it now.
I can use the ones you stated or the Bullseye, just use cast loads to keep velocity down a bit. There could be one of two theory's.
1st Where the velocity peaks inside the barrel
2nd Where Velocity is still peaking nas it exits the barrel.
Either one, needs the chrono which I do not have as yet. Have to grab one from someone elses toy box.
Keep It Simple Stupid (KISS)
Use pistol powders.
Use Cast recipes and/or keep charges on the lite side.
If possible, go to jacketed bullets
