no insult intended about the nail; but i am trained to not make assumptions. sometimes i may take it too far. you didn't sound upset, but i'm thinking that maybe you didn't need any admonition at all......
do you shoot double-base powders with nitroglycerine in them? i know that they really dirty up the firearms that i use compared to the single-base stuff. i have, for instance, loaded imr 4320 in a .30-06 and seen the brass and rifle develop Very Little powder fouling, while the double-based wc-846 i usually use in the .223 and the .308 are very dirty. i try to keep up with the powder fouling every time i'm done shooting. i may not use a brush as much as some other guys do, but i do get the powder fouling out. some of the long-range/match shooters are using the General Motors product that breaks down carbon to start the cleaning process with their rifles. i'm going to stick to marvel mystery oil because it's so effective for me; but it does speak to the fact that carbon is a problem that can be dealt with.
just a thought,
