Hi,
I've been lurking for months now, but this is only my 7th post--please forgive if I violate some protocol! Anyway, I'm having a problem that I hope someone can help me with. First the background: I'm casting my boolits from wheel weights for .45 ACP, 9mm and .380 Auto. I powder coat with Super Durable Wet Black from Powder Buy the Pound using the shake & bake method. I get decent coverage with one coat, but if I shine a flashlight on the boolits I can see thin spots. I then size the boolits .001" over groove diameter (as determined by slugging the barrels with a soft lead slug). My loads are as follows:
.45--230 gr. boolits with 4.8 gr. Win 231
9mm--125 gr. boolits with 4.2 gr. Win 231
.380 Auto--95 gr. boolits with 2.8 gr. Win 231
I use either Winchester or CCI small pistol primers (standard, not magnum). My pistols are a Sig P220 (.45), a CZ 75B (9mm) and a Browning 1911 .380 Auto.
After I shoot the pistols, I usually run a bore snake through them to remove most of the fouling before I clean them thoroughly. After I do that, I can see that most of the barrel is pretty clean and shiny, but there is a thin smear of something left in some places. Here's the part I can't figure out: The fouling is only in the grooves at the REAR of the barrel, and only on the TOP half of the barrel (the "ceiling" of the barrel). It extends about 1" and then the rest of the barrel is clean. The fouling can't be removed by pushing wet patches using a jag, and it can't be scrubbed out using a nylon bore brush with solvent. It can be removed without too much drama using solvent and a brass brush run back and forth about 10 times. I have used a variety of solvents (Hoppes 9, Remington 40-X Bore Cleaner, and Rem Oil); they all seem equally effective.
I should point out that this is sometimes a problem with the .45, but ALWAYS occurs with the 9mm and .380. It's not a huge issue, but it puzzles me, and I hope that someone can throw some light on the situation.
Thanks in advance!
John
