Nice report there, Ausglock. I'm anxious to see how they shoot in your 9mm especially...and the condition of your bore afterwards.
I don't own a 38 super, but I feel like I kinda walk a tightrope with my Kahr PM9...getting enough "juice" to reliably cycle 125 grainers, and not so much that I'm leading. (With 45/45/10 Recluse lube.) My best wheel weight load for the Kahr has been an odd 163 grain flattened round nose from an old Cramer over about 2.9 grains of Bullseye. I don't have a chrono, but they cycle and leading is light with LLA and Recluse Lube. I'm SURE the velocity is low and so is the Point Of Impact. The Kahr is my everyday carry piece, and if I *KNEW* for sure that Hi-Tek coating would make it shoot PB (practice rounds only) without leading and acceptable accuracy, I'd be reaching for my wallet.

P.S. Another question is with collecting and remelting of these coated pills (which I do regularly in my 5 gallon rubber mulch traps). Do they melt OK? Is there a stench or additional health hazard? I should have done a forum search for that one, but I didn't.
