Re: Fouled bore ?
My routine with Bore Tech is I liberally wet patch with Eliminator until the patches start getting light blue. Then I push a nylon brush all the way through and bring it back just inside the muzzle, then stand the rifle up on it's butt and drop a libral amount down the bore, then scrub for a few strokes, maybe 5 or so, then let it soak for 20-40 min, then wet patch out and repeat the cycle until I see no more blue. When I stop seeing signs of carbon, I swith over to CU+2 to finish the process.
Your bass core brush might be introducing a false read. You might want to go out and get a non-brass core brush and see what happens. Does your rod have a brass tip?
You will never know how much it has cost my generation to preserve your freedom. I hope you make good use of it.
