I had to shave 1.5 thou off just above the rim for 5 mm on some cases I made from 3030 to get them to chamber, admittedly they had been fired in a rifle beforehand. I assumed it was a tight chamber but maybe not. By the way 17 gr of 4227 gives me 1470 fps

What are your groups and ES like with 4227?
