I recently bought a rcbs 150 cowboy mold plain based(no gc) and was needing some info on powders to push this thing. I want the velocity up as high as I can without leading. I've tried unique, and it works well but I'm not getting the velocity I need to correct the open sights. I am pan lubing as cast(310") with a 60/40 mix of candle wax and petroleum jelly(it works great!) and loading in a winchester 94 30/30. I'm not against getting a gas check design, as I have the notion of ordering a 311041, but I was wanting some real world information on this subject, and to be fair I scoured the archives here before posting. Thanks.
