FWIW, the first rounds I ever fired through the above-mentioned 10FP were from the Tubbs fire-lapping kit. I loaded and fired the full sequence of progressively finer-abrasive coated bullets, I think it was fifty in all. Been quite a while so I don't remember if it was fifty, or twenty-five. Anyway, they had absolutely no visual impact on the chatter marks at the muzzle, so don't buy these expecting any miracles. I can't say if they improved the throat area or not. I don't have a bore scope. Nor can I say if the barrel would have shot as well had I not used them, as the barrel was new when it did the "fire lapping".
