Choices
Varget
CFE223
H4350
Winchester Staball 6.5
IMR 4064
Which powder would you choose to start with first?
Check Hodgdon's website, all of the powders you listed give good to excellent velocity with the weight bullet you've selected. I have personally loaded Varget, H4350, and Staball with 139 gr Horn SPs and have gotten the best consistent results with H4350, also with a little more velocity than their data showed. Enjoy that cartridge it's a dandy.
