Quite simply, this thing is WAY oversize (it comes in a 1in ID plastic tube that is a firm fit...) Someone in the "Hoppes physics department" must have forgotten to realize that an oversize mop gets more oversize due to friction as it moves down the barrel.... I could never get this thing down my entire 28 in barrel, even coated entirely with CLP. If it were .800 or so, I think it would be a great tool....
Pros: looks cool
Cons: dosent fit bore
