Hello everyone, today I was finally able to get a decent group at 150 meters with the Mauser 7.65. Approximately 1.5 or 2 moa. I did not have an opportunity to measure the speed. The charges were made with H2400 15, 16.5 and 18 Grains. Brass FN Berdan. RWS primer. Practically the groups were the same. I tell you that I also did a barrel slug and bought me a micrometer. It gave me .312 in its widest part. Currently I have a mold Lee .312 with a .311 Lee bullet sizing kit.
Should I improve the grouping if I leave the tips as they come out of the mold?
I was thinking of taking a specialist bullet sizing kit to enlarge it to .312 or .313. And so I can put the gas checks
Is it a good idea or a crazy idea?
