I’m looking for some powder to start loading for .38 special, using a 12” barrel Taurus revolver.

I’m going to be shooting gallery rifle, at 25m max, so I’d need to be downloading the cartridge.

I have some unique powder but was advised that this will probably be too slow burning to use effectively, as I would need to put lots in, which would result in unnecessary recoil etc.

So, I’m after a fast burning powder, I have GM3, which I use for lever action .44 mag, this is quite dirty, so not best for a pistol.

I was advised to get CSB5, N310 or N320 but my local shop doesn’t have any of them.

So if anyone has any suggestions for a good commonly available powder for pistol loads that would be great, thanks!
