And to the original concern about cylinder face wear, this is a function of pressure and temperature and the volume of gas blowing out of the barrel/cylinder gap. Winchester long bragged that its spherical powders were a little cooler burning than stick and flake powders, so Winchester 231 (HP-38 is the same powder, but packaged with the Hodgdon branding) should be a good choice from that standpoint.

Powders with flash suppressants should also be on the cooler side. If you are going to try a slower powder, see if you can lay hands on BE-86, which is a low flash powder. Most such powders have nitrosoguanidine or a related compound that lowers flame temperature some.
