Re: Cleaning loaded cases
Clean the lube off your cases before you prime, charge and bullet them. Use laquer thinner in a ventilated area and set 'em someplace warm to evaporate the thinner off of them.
There's mixed opinions about tumbling live rounds; SAAMI and powder companies say not to do it. Same thing on wearing seat belts in cars, some people choose not to. We all get to define our margin of safety. Like the sign in the motorcycle dealer's sales room said: "We have no argument with folks who don't wear helmets riding these bikes; they know what their brains are worth."
