I'm pretty strongly convinced about the comparisons often made between 45/70 & 444. According to some sage advice from long time reloaders, you can do with a 300 grain bullet in the 444 what you can do in the 45/70 with a 400 grain bullet. So, that brings up the question about using 400 grain Creedmore style cast in the 444 for long range work. Does anyone here use Creedmore style cast bullets in the 444? Would FlatTop's Safari Upgrade allow Creedmore bullets to cycle or would my 444 become a single shot for Creedmore bullets?
