G'Day Fella's,

Its a good idea not to use any abrasive bore cleaner any more than is absolutely (Well look at that, that "A" word was actually used in context for once!) necessary.

That should mean- As Your Last Resort!

As Daryl S mentioned, the black, black, black that keeps coming out is actually a combination of both the abrasive bore cleaner (now, broken down) and the inside of you barrel!!!

So if you like smooth bores or something that actually looks similar to H&K Polygonal rifling, keep over using the abrasives and this is what you will end up with!
But I recommend that you start with a .270 caliber rifle, as you will eventually be able to shoot 7mm bullets through this New Wildcat caliber?
