Kelbro,
Was your leading in the first inch or down entire bore?
RecoilRob,
Very good point. Do you have any personal experience with manual lapping you could share with those following this thread?
Also, I have tried Oregon Trail, my ww home cast, my friends ww home cast, Sierra lead, all prior to my current use of Missouri. All leaded! Even a few gas checked boolits leaded!
Only thing that didn't lead was jhp, but then there was copper fouling!
I've done some sandblasting in my day, probably more than I cared to, and found the sand lost a percentage of its cutting efficiency after the first use (recycling sand, like in a cabinet blaster). I figured the most aggressive cutting would occur at the point of first contact and demenish progressively from there. So the later part of bore would not lap as much as first inch.
Anyway, I feel with 20 more this weekend I should start seeing some real results. Like I said leading has already been reduced from the normal manual chore. Another 25% would be great and accuracy does not seem to have suffered.
The testing continues!
