I agree with JE.. I never understood how cleaning a barrel can be more abrasive or more damaging than a bullet whistling down the barrel at over 3000fps...You hear all these guys say that cleaning is more damaging than actual shooting?!
I like the idea of that wipe out stuff because its easy, not because i think its less damaging. That's like the whole "barrel break in" crap... I probably just kicked over a bee's nest..but I just don't believe in it because there is no evidence or facts that proves that barrel break in is effective...
Barrels will corrode if left dirty and I do believe cleaning religiously (not everyday, dont clean it if it isnt dirty) but I am also not a target shooter. As a hunter, I clean after every hunt.. and when I clean.. I CLEAN!
