QUESTION..

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 .

[Mark Garrett]

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
