I have been trying to come up with a good combo of lead and powder for my .22tcm reloads. I tried casting 50 grain .22 bullets and tried using varmit grenades but none worked all that well. So today I bought several boxes of this .22 ammo to reuse the bullets and then use the brass ( once cut down ) for percussion caps for one of my muzzle loaders. But I would also perfure to reuse the powder as well. If I knew the burn rates etc. for the powder I could use the load data for whatever powder is similar.
Any ideas?
I am thinking it may be close to power pistol? T I A
