app or 777 in fffg
I have a omega 50 cal and would like info on using app 3fg. I understand that app is cleaner but is it as reliable and consistant burning as 777. I also wonder if changing to the small cal rifle primers will work ok. I will be trying to get better acc out of this gun using 300 to 330 grain bullets.I would like to get 1 to 1.5 in grooping at 100yds. do I have a chance of getting this from app or 777 in 3fg ?
