I shoot 4064 in my 270 with no other powder coming close to its accuracy. 1/2" 3 shot groups at 200 with a factory barrel in a tupperware stock. If you can't find a node in 2 grains and don't know when to stop...don't ask reloading questions on the internet.

Edited:
So I looked up hodgdon and they do say that is hot. I had looked at my reloading log as well and saw 42.5 but a second look said that was for 4064.

I used Hornady's current(IIRC, 9th ed).
But the greater point, which I didn't make clear is the actual pressure.
Rather than focusing on grains, which no one but the handloader loads to, is the velocity. For the average Joe, the velocity listed will be what keeps you within pressure limits.

Unless any source lists the lot numbers, which none do, the only way for us to watch pressure reliably is with the Chronograph. Varget may well work, my only concern is that it is getting pretty fast.
