EDC: SIG P938.
I posted a couple of months ago that I had cleaned my barrel, after 1000 or more rounds of moly/poly "black bullets", by merely scrubbing it lightly with a bore brush. I cleaned my barrel again, for the first time since that last post, and after over 500 rounds, and . . . Same thing. 15-20 strokes with a dry bore brush, and there was not a trace of residue in the bore. I was paying about $60/1000 for Precision bullets, but found a local maker (masterblasters.com) who sells them for $44/1000 (no shipping) for 230gr RN and TC. These are not "moly coated" bullets; they are completely encapsulated by a hard "plastic" coating that contains a molybdenum lubricant. They are as easy to handle and load as jacketed bullets, and are as inexpensive as cast lead. Try them.
