I created a thread a couple months ago about this and did not get any response, so I am going to try again. does anyone know what the psi rating is of factory AA loads, Winchester does not publish this info and says "it's proprietary". The factory load I am shooting is 20 gauge 2 3/4 shot size 8 rated at 1300fps with 7/8 oz. load. Any help on this would be greatly appreciated. Thank you, Joe

According to SAAMI specs., all 20 gauge loads are 12,000 psi., max. That includes loads from 1165 to 1570 fps., 2-3/4 and 3" shells.
