Very nice batch of molds!!
I had a very nice 310g 452 WFN mold from LBT once. Either misplaced or loaned out and cannot find. I still have some bullets. Wish I had now to experiment with PC it was a good design for PC. I picked up a LEE 300 as a quick replacement (better size wfn) but the bullet is fat and requires deep seating in most guns.
I borrowed a RD 300 mild and cast up about 500 and that one is better but still not perfect after PC. My Rossi 45 LOVES BOTH!! My Marlins do OK with Lee and great with RD my Ruger shoots both but requires deep seating. I dont usually feed my SAA, such heavies they wont take either bullet with out a deep seat. That included a Colt New Frontier.
