So couple days ago I shot 100 rounds of 45acp(reloads). 50 of them I used w231 and the other 50 I used bullseye. When I got home, I took apart my 1911 and I was surprised to see how filthy the gun was. I actually had to scrape the crud off of the barrel and frame before and after I scrubbed it down w/ some clp. I never had experience with carbon like that before. Is BE a dirty powder(my first time using it)? Or was it a combination of both powders that made my gun that filthy???
