I have never been a huge fan of the Louverin style boolits. For what ever reason, (maybe because I shoot mostly modern rifles and few older military rifles?), I have always had more success with other designs. I've tried a number of them from 22 up to 30 caliber, and some shot well, but never as good as others for me. Maybe just my loads or technique, I dunno. But when I read beagle's article on Castpics about the RCBS 30 SP molds, it piqued my interest. He compared the older RCBS designs to Louverin's, and they do look similar. I decided I would look for some of the 30 molds to try. Not long ago I bought a 30-180-SP of the older style on here from no.1.
Then the other day I bought a 28-168-FN RCBS mold thinking I would try it as a heavier boolit in my 7-30 waters contender or 7-08. This is the mold I received. It immediately reminded me of beagle's article and the Louverin comparison. I've begun to call them semi-Louverin's. The left mold is the 30-180-SP mold I got from no1, on the right is the 28-168-FN I just received. It came in one of the old RCBS green and white cardboard boxes. Anybody know if RCBS made any other of these "Semi-Louverin" designs? Just curious. Thanks, Billy
