There's lots of shooters who write about using the highly regarded Keith load of #358429 bullet with 13.5 gr. 2400 powder in .38 Special cases in their .357 Magnum revolvers (in order to allow the long bullet to work in the short cylinders of some of the weapons). Usually such a setup can cause a build-up of crud in the chamber throats because of the shorter case length, but I never hear about this as a problem when the Keith load is used in a .357 Magnum. For those with lots of experience using this load: is it somewhat immune to the crud build-up, or do you just brush it out of your chambers and not talk about it? Thanks, GWW
