Well there ya go, goes to show you how many different ways and ideas we have about barrels. I know that COBrad knows a lot more than I do, and like he said, he gets his tubes clean!
Maybe I'm just too lazy to scrub 'em
But IME thus far, my rifles like to be shot fouled, and after I clean, it'll take a shot or 3 to get back to 'dirty enough'. Perhaps it has something to do (or everything to do) with the quality of barrel used, as most of the stuff I'm shooting is just factory barreled. No doubt that those nice, smooth custom pipes will shoot great clean, but then again, some of those rifles will shoot rock salt into tight groups... grin
Anyhow, I hope you gentlemen are busy making final adjustments and what-not to your elk hunting rigs, and good luck this year! I've got one more load to create before the 13th, thinking 180gr Ballistic Tips in my Grandpa's M70 300 Ackley.
