I have shot the larger bullets (312-314) in mine, but the pressures do increase quickly and I got a little more fouling. I found the .308-309 bullets to work better, give better accuracy and were more desirable for me. My cast bullets for my barrel, were more accurate when sized .310. Just my opinion.
If you want some good loads, try the sierra 110hp pushed with a little unique or accurate #5.
