Hi, again....
Thanks again for all the previous advice. The two molds I' ve been having trouble casting with are getting better. Starting to get less rejects with both the Lee 230RN TL and the 38 105SWC's.
The problem is we are still getting lots of leading with LLA and all the bullets. Even the 45 200LSWC-TL's and 9mm 124LRN TL.
Tried seeing if there was a difference with water drop vs air cooled. Tried sizing to .357 (for 9mm) vs .356 and .452 vs .451 for 45. Tried different loads of 231 and even tried different depths. All to no avail. They all produce a lot of leading. We even tried adding tin/antoimony solder to increase the alloy.
Is it maybe the whole batch of WW ingots were no good and should start over?
Didn't have this much leading before when I was just air cooling and not resizing. But that was only one batch that was ok. The rest were cast by a friend years ago.
The only thing I haven't tried yet is changing the lube to something other than LLA. Two guys have been using that stuff for years and can't figure out why we are getting so much leading now.
