Re: Cleaning of Dies
I clean my dies with a bronze pistol bore/chamber brush wound with fine steel wool. I follow it up by replacing the steel wool with at a wound-on shotgun cleaning patches (one at a time). I'll replace it at least 2 or 3 times. The first one will be moistened with rubbing alcohol, and the last one will be lightly moistened with gun oil.
For most chamberings using a .473" bolt diameter, a .45 caliber chamber/bore brush works, for smaller (.223/7.62x39, etc., I like a 9mm bore/chamber brush.
I keep a small vial with patches and add a few drops of oil. By the next time I'm ready to sue the patches the oil will have spread out quite a bit. I keep doing this on and off until the patches are evenly but lightly oiled.
It's important to do it as part of the tidying up at the end of the loading session. I use water soluble lube and it can attract moisture, so I like to get it out of the die pretty quickly after usage. My dies are pretty glitzy between loading sessions.
