There is obviously something more going on here than either titegroup or SNS quality. There are just too many of us here that have loaded many thousands of rounds of cast bullets with Titegroup and SNS coated bullets with zero issues. I have been using both for a long time (been using SNS since long before coated bullets were even available) and have been absolutely pleased with both powder and bullets. I think rather than a blanket warning about fast powders (titegroup) they should have recommended that those with leading issues have their bores slugged. By the way, I ordered bullets one time from ACME. Cute little wooden boxes and all but, the lube had fallen out from almost every bullet and they were pretty much unusable. I suppose that wouldn't be an issue now if they're using coated also.
