I'm very interested in this 38/44. I find r RR for rrr b for. very little about it. I did read about seating to the bottom crimp. I have this same mold. Lyman 358 156 in single cavity. Gas check. Are these 38 44 the same as plus p loads or completely different. I would like to try some in my Rossi 92 and Smith 686. 6 inch barrel. With this bullet how do you determine which crimp groove to use. Be waiting for replies. Thanks Johnny
