These loads are all 2 1/2" in Cheddite paper hulls with Cheddite primers. I shot some similar loads worked up with bismuth shot in 2 1/2" Cheddite plastic with Fioche 616 primers, roll crimp, first in my Winchester then in one of my 12 ga. Parkers. The bismuth was 18 gr. Green dot. Mild, and chrony at 1060 FPS. Had no issues of any kind other than they didn't want to cycle well in a 3 1/2" magnum gun, insufficient recoil/pressure to properly operate the mechanism. No surprise there, did cycle in a Winchester 1400 I have that will eat anything 2 3/4" or 2 1/2", dirty, sandy, mildly rusty, or generally disgusting ( a tried and true duck killer I've shot for years, a saltwater gun ugly as post hole diggers)!
