I'm using Starline .38 Short Colt brass, TK Custom moonclips for Starline brass, and 160gr. Bayou round nose bullets. Reloads are very fast. You need to match the moonclips to the brass on rimmed ammo. Not as critical on rimless. Roundnose bullets are a must. If they have any flat on the end, they tend to hang up. Shorter length cases help. Easier in, easier out.
