Going bonkers over my 98

[Rapier]

"After every 3 round shot group, I clean the barrel using my Otis cable system, running the brush through five times with Break Free, then pull through the patches through until they come out clean."

Jon,
The military has Break Free everywhere. I wish I had a dollar for every young GI with "found" Break Free that showed up at my Rod and Gun Club range while I was the range master there. They could not hit a bull in the butt with a base fiddle with their "cleaned" guns. You just got a lesson in Break Free in a bore, first hand. Bad news is this, I have seen it take many, many rounds to clear the effects. The crap will not come out any other way, but to shoot it out. It is a lubricant that contains a polymer and it coats the inside of a bore......it is not a bore solvent or a bore cleaner or a proper bore treatment, and never has been or will be. Put it all over your gun, drink it if you wish, but do not put it in the bore of a gun.

Go get a shotgun solvent that dissolves wad residue and scrub the pee out of your bore, it might help, that is might. Otherwise, shoot and scrub, shoot and scrub with Shooters Choice Copper Solvent, unitl the accuracy returns.
