I know this is an old post but I just purchased the same mold and I'm getting the same results with my alloy. I'm still in the process of attempting to locate some load data.
I have been looking for some load data for a 160 grain molycoated bullet, I have been told there was a wealt of information in the older Hodgen manuals. I have a huge supply of HP-38 and was hoping to get some data for this powder / bullet combo.
Anybody else using this combination of something similar.
I have been running 135 Bayou with 3.9 grains of HP-38 with an OAL of 1.130, nice load.
I have started casting some 160 grain bullets and I'm looking to give 2.8 grains of HP-38 a try, any thoughts ????
