I buy cast bullets from Penn bullets. 125gr LRN I'm useing BullsEye right now. I have leading problems with 3.3gr of powder. Penn suggested slower powder, so that is on my list. I haven't figured out the perfect OAL but 1.125 is what I'm using. The 3.3gr load is not giving me enough obturation, so I thought that maybe 4.0gr of Bullseye would be good. After Bullseye I was thinkling about HP38. Opinions welcome.
