Hello all and thanks for the nice words, RR.
Alan, your experience exactly mirrors mine when using cast bullets in the HP! When I cast my own out of pure linotype, the leading went away from the form before only to remanifest itself in the form of "stalactites" hanging down in my bbl after but a few shots! Cast bullet loads will work in the HP, but expect some leading. I have never found a cast load that will match the grouping ability of several better jacketed loads. IF you really want to shoot cast bullets in the HP, I suggest going with the BarSto bbl. It's lands and groove dimensions are said to be more tolerant of lead and I know that the 1:16 twist is better for such rounds. I do shoot cast bullets in my HPs, but only when shooting in bulk for practice at larger targets such as self-defense practice at IPSC targets. For a match, I'd go with an accurate jacketed load at the same power level or more. Coating lead bullets with sprayed-on moly has helped reduce leading, but has done nothing to help (or hurt) group size. Best.
