A buddy gave me 1000 Dardas bullets, DEWC 148gn, 16-18 BHN, for 38 special cast to 0.358. I loaded them for my new S&W Model 66 with CCI Primers and 3.0 gn of Tightgroup. The OAL was 1.230. The pictures were taken after just 24 rounds. Could someone tell me where I'm going wrong?
I new to using cast bullets, and was hoping to get into making my own after these were used up, but the amount of leading here seems excessive. Any Help?
