Try the 65 grain Vmax. I do know that you can push that up to 3500 plus. Whatever you do, let us know...we all like to hear about what others are up to. Good luck, have fun, and be safe!
I just looked at Hogdon's Data and i don't know why i was thinking 3500fps with 75gr. bullets. It looks like H414\Win760 at max load (46gr.) will get me to 4447fps book value. Out of my 22" barrel I'd guess about 3300? That's plenty fast for me. I think i am going to play around with Win760 or H4350.
