The Bore Scrubber

You guys ever run into this?

I shot a bunch of test loads that left moderate leading in the bore with lead streaks to the muzzle, (an unacceptable amount for only 50 rounds.) So then I ran through another forty or so of one of my favorites: A #358477 over AA #7. In this case it was 10.8+ grains, and the bullets were near linotype in hardness. By the time I was done, there was barely a smudge of lead left in the bore.

Now I've had loads that progressively deposited more lead, and most stay about the same after the first dozen rounds... but progressively better?

How many do you think I'd have to shoot before the gun was restored to NIB condition?

it's in the boolit fit,not the hardness
ive had to shoot the opposite to clean up leading from too hard of a boolit,that was too small.

Cream of wheat as filler will scrub the bore also. Loads need to be reduced and used with caution. DALE

A handful of Berry's plateds applied at book max velocity is my answer.
I know I'm not casting them, but what works, works.

Paper patched bullets will make the bore shine also.

Firing a few gas checked boolits does the same thing.
