Thank you for your help, in advance.
Loading up cast bullet loads in 40 S&W with Lee 401-175-TC, has single lube groove, lubed with 50-50 NRA formula, shot out of an H-K USP. So far have shot ten or twenty boxes with this load.
I cast my own, and use a Lyman 450 lube-sizer. I have loaded thousands of 38, 357, 44Mag, and 45ACP using the 50-50 lube. None of the cast loads have had lead fouling or lube fouling--until the 40 S&W.
No leading, and good accuracy, but getting lots of lube fouling right at the step at the end of the chamber. This then prevents the next round from chambering. At times it gets so bad we have to stop and scrape it out within 20 rounds or so, sometimes 100 rounds are OK and feed normally. It's like hardened lube mixed with carbon fouling, comes off in chips and chunks. This does not happen when I shoot my standard 45ACP cast load in a 1911 or Glock with 50-50 lube.
Looking to change lubes, would like one that does not need a heater for the lube-sizer.
I welcome your opinions....looking to try White Label Lube BAC, 2500, or Carnauba Blue.
