Hey man, I don't know about a guru but I do enjoy reloading! Keep your velocities low with cast bullets, they do craaaazy things when you try to push them. Other than that, have fun with em! As long as the cast bullets are lubed the pressure shouldn't be different enough from jacketed bullets to make any noticable difference. As far as cleaning goes, I've used krol oil-I think I'm spelling it wrong- with great results, It is a penetrater and gets down under deposits that other cleaners can't. Let it sit in there for a while, then take the barrel out and really scrub it. If it still doesn't get out, try coke. A gunsmith I know uses good old coke-a-cola to get stuck bullets out of barrels. Plugs up one end, fills it up with coke, and it actually eats away at the lead until you can push the rest out.
So do you cast your own?
