not much factory 230 fail safes old stuff 250 power points and 210 partitions fed load just started playing with 230 eld and a lot of different powders
but for some reason in my gun if you try to push them fast it's 2in or better 10 thousand off lands so i worked down from there and got good results at 73 grains. but i also had a break installed on it so not sure if that made the difference or not
