Looks like for now the lighter bullet idea had been quashed .
Already have the Castboolits group buy 434-207GC which has killed several deer from one of my 444;s and shoots nicely in the 336-44 .
Have both the Lyman 429215 (210 grain SWC GC) as well as the RCBS 44-225 GC SWC . And just recently added a nice old Lyman single cavity 429434 which is in all actuality a 220 grain RN FP GC bullet that was originally designed for the 44-40 . This one drops at .430" from the mold with aircooled WW"s . So while I would wish for perhaps 2 more thousandths in bullet diameter I should still be able to make it work well enough for deer inside 100 yards .
But who knows down the road I may decide to go on and get a MM/RD mold in the 200-225 grain range
