Thanks RK.
I think the "Dust" looking patch is from the cotton. I stuffed a whole cotton ball in the bore, you know stuff, twist, stuff, twist then push thru with a non scratching Ram rod.
I think i might work on that one tonight with the lapping compound and cotton . Good Idea. I may do the same with the newer one too, to keep from shoot lapping again.
When I slugged the bore on the non grouping one it measures .440 lands, and .446 or.447 groves. I'll slug it again to be sure. It does group to some extent, but not near what the newer one does,
I mean I am slap HAPPY with the newer one.
