Hello John,
I am searching for your article in Handloader Magazine about the potential velocities variations, in more or less, changing the case capacity in the same caliber, or the same case with different caliber, or changing the bullet weight, or a mix of all these. I cannot find it. If you can give me the number of that HANDLOADER Magazine I will appreciate a lot! Or, may be better, tell me here about that "rules".
Thank you!
