Unless it's some kind of uber-expensive tactical rig or sniper rifle, (and even then, it's really a more of a "better safe than sorry" kind of thing) I just don't get all the obsession with "grit" and the "wrong" kind of rod.
As long as you don't beat the barrel at funky angles with steel cleaning tools, just what kind of damage does everyone think they're capable of that a bullet moving a couple thousand fps, and pushed by a couple thousand psi., gasses burning at around 2000 degrees won't do?
Maybe we shouldn't be firing the rifles at all. That's the sure way to prevent wear on the barrel...
Other than not shaving on the crown with a rod of equal or greater hardness than the barrel, or using a rusty bent Comblock SKS cleaning rod with a hammer, just what is with this obsession?
