Re: cleaning brass?
Use a walnut media that measures .015.( It will vary between .010 and .020 when
you measure it) I use frankford arsenal polish which has a citric smell to it, but there
are many others, just stay clear of ammonia based ones like brasso. 10 lbs. of the good media will last a half a lifetime for a moderate to heavy shooter. With a rotary
media separator like a dillon you will have 0 media stuck in the flash holes. I de-cap,
tumble for an hour, prep the brass completely and tumble another hour. Blackened
brass (old range pickups) I soak in vinegar and water (50/50) until fairly clean. That
oxide is literally as hard as iron and you don't need it in your chamber.
