Your load is a low presure load ( guessing 7000 psi or below ) Bismuth will give you a taller shot column and more pressure . Using Bismuth in that load shouldn't give pressures above 11500 psi . Probably a lot less , but estimating what the actual pressure would be is just a guess without getting it tested .
That same load would work with niceshot . |

personally Angel- I'd pop for a book
why risk it i know that nice shot says to use a lead load and plan on 1500PSI increase I am not sure I have seen a formula for the difference with bismuth or at least- pick a low pressure lead load - make a few up and send them out to be tested

The only load that I could find for reference use a different wad and a 2 3/4" hull .
Win poly hull (same as Ched ) Win 209 - 22gr 7625 -Z16 wad - 7/8 oz bismuth 1264 fps - 7400 psi - Precision reloading I find the z-16 wad will usually give lower pressure for the same load using the Sg16 wad |

Thanks a bunch guys. That gives me something to think about. I guess I better see if Ballistic has a book with some recipes.
I guess going from 2-3/4 to 2-1/2 would increase the pressure? Can I go with 3/4 oz of shot instead of 7/8?

Angel you can use 2 3/4 inch reloading data in 2 1/2 (preferably 2 9/16th inch) shells if you want to go to the trouble of roll crimping as the 2 9/16th roll crimp shell has the same interior volume as a 2 3/4 inch folded crimp shell.

Hoe does IMR SR-7625 compare to Green Dot and Unique?

Angel as I understand it they are doing away with SR7625. If I were going to develop new loads I would try powders that aren't going to be obsolete. JMHO
