Hello 1911 Fans. I am going to take a carry permit class over the course of 2 days. I anticipate shooting 500 rounds. I am a at reloading. My question is “ can I use the load data from the 40mm with less powder in my 10mm case. Same powder, same bullet, bullet weight, and primer, different starting load powder charge of 3 grains between the 40mm and the 10mm in 1911. Will doing this raise pressures to an unsafe level. I trying to make a reduced power load because of arthritis in my wrist. 500 rounds in one or two days is a lot for me. Has anyone tried this yet?
Mr Thomas
