Well I'm new to the group but have cast pistol bullets in the past. tried 30-30 with a Lee 309-170 mold and cast from mostly wheel weights. coated with hi-tek and they came out good. loaded some plinker loads with 10 gr. unique sized without checks and some sized with checks loaded with 24 gr. 3031. first few light loads shot OK but started to feel chambering issues. figured maybe neck not expanding with low pressure. Letting gasses back into the chamber. went to some 3031 loads and shot a lot better but more chambering problems. pretty hard to see bore late in the evening in a lever action- nearly new Canadian commemorative 94. at least hasn't been shot much and started out with a clean bore.now I have leading streaks to try and get out which may take some time and without diss-assembling pretty iffy to tell if I have the chamber clean. is it even worth the problems to use such loads? I have read of others having good results with these loads but I am having second thoughts about the coating
