I bought one of these from Natchez for my new Mini-14 and a couple of .22LR's. I tried it first on a .22 pistol and it wouldn't fit. At all. Then on the Mini (which has not been fired yet, so it's clean) and it took several minutes of frustration to get the pull string down the barrel, then when I tried to pull the green part thru it only went about 2 inches and got stuck. Like maybe the knot is too big to fit past the chamber. So I pulled it out backwards and put it back in the package so I can send it back.
I see there's an 800 number on the package so I'll call Hoppes tomorrow and see what they have to say about it. I know it has to be tight to work, but this felt like it was going to break off in the barrel if I kept pulling on it. (how would you even get something like that out?)
I wonder if this is a 6mm or .270 cleaner in the wrong package?
