If you ventured a guess, what do you think max velocity on a 5" 357 mag revolver will be with published max loads?
I chrono'd 1300fps with Alliant 300MP powder, but was 1.1 grains lower than max published data from Alliant's site. I'm going to be carefully working my way up to max published and am curious if I will see more velocity over chrono. It's going through a GP 100 so I am confident weapon is strong enough.
