I'm just about out of Win 231/HP-38 powder for loading 9mm minor and 38 special. I've looked at Ramshot Zip as a replacement powder; cost is the same and the burn rate is right beside Win 231 so nothing gained or lost on those two points. Those that have tried ZIP, is it any cleaner burning than Win 231? I would switch for that reason alone but if no different, I'll just buy either from the closest retailer.
