So maybe I should shoot for 59gr of IMR4350, which according to Nosler, with a Partition, ballistic tip or ballistic silvertip would be 3028fps and 80% density. With the E-Tip, they say to reduce the max charge by 2gr, so my max charge would be 61gr. I think I'll give them a call in the morning and see if, with the E-Tip, can the charge of IMR4350 go down to 57gr, and if so, what would the velocity and load density be. Obviously, if my starting attempt doesn't cycle properly, I'll have to bump it up.
Dumb question, sorta on topic. Nosler says there needs to be a minimum jump to rifling of .050". How do I determine this? Load a dummy round long and chamber it, then reduce its length to allow at least .050, assuming I see rifling marks on the bullet?
