4064 is a good old powder, accurate.
IMO, there are better powders now available. I like Big Game in my 7-08, like Pharmseller's loads, groups and dead critter portfolio.
H-100V is a velocity winner in my .257R with 100's, and top accuracy,
4064 will work in a bunch of applications, optimal in some, such as the .416 Rem.
