Thanks for the feedback Mike. The short answer is that 32 is between 22 and 38. Those bases are covered pretty well. I'm looking for something novel ( atleast to me) and i know the HR's are pretty well made. That said, as a reloader and caster i can work with a wide variety of components including black powder. I think the 32 would be fun and relatively inexpensive to dink around with.
i had an old(1902), 2.5" iver johnson top break in .32 s&w(short) that was my great grand fathers. i scrounged 50 brass, and borrowed a 90gr swc .313 mould. cast 200 boolits.
loaded with black powder it was such a smooth shooting gun. very gentle recoil.
