Jason,
I shoot an 1881 lifter Parker 12 gauge on a #2 frame with Twist barrels. I started shooting reloads at around 5100 psi and below. At the Southern a few years ago I shot factory 2 3/4" Winchester AA XTRA LITE 1 oz loads. In the reloading manual they are about 7200 psi and someone said the factory loads are around 8000 psi. I have more Winchester WST powder than IMR 7625 at the moment and am shooting the 1 oz loads at 7200 psi. I will shoot 100 plus rounds a week through that old lifter. If I could afford factory loads I would shoot RST's 2 1/2" shells. I still have a few and save them for special occasions. RST's are better than anything I can make at home.
