If you can get me the bullet dimensions, mainly the length and diameter. I’ll run it.
For this we’ll assume the shank is the full length of the bullet (Basically a Wadcutter) that way you’ll see results that are a little more on the conservative side ;-)
With AR’s CFE BLK and A1680 (Two very similar powders) are really handy powders because they generate a lot of gas, and hold onto pressure long enough that they cycle the action. Faster burning powders may not cycle the action.
Lil’ Gun can often be an excellent powder for magnum cartridges but you may find it a bit fast to reliably cycle the action.
Reloading...it’s like knitting for men.
