I'd say your .54 likes a high fat diet!

You know, even though I'm partial to spit-patching I do swab w/bore butter( I know,I know) after cleaning; that first shot leaves very little residue. Your patches look very clean.

Just the other day I was at a fabric store purchasing patch material & had denim on my mind but it seemed real thick, well beyond ticking, so I passed.

Now, speaking of patch thickness, & not to hijack HA, but the CVA Plainsman I just picked up has me wondering. A .50 ball does not roll down the barrel bare, has me wondering about patch material. The bore is clean and new.
