Do any of you smart fellers out there have any experience with vihtavouri powder N 160 or N 165 for 160 grain Barnes XLC bullets in a 7 X 64 or .280 remington?

I sure hate to run out and buy a bottle of N560 or N565 just to load up one caliber / bullet combo, and the book doesn't list the regular N 160 powder.

Just wondering?

I know this isn't exactly what you asked but my manual states that with the 160gr Nosler the MAX for N160 in the 7X64 is 57.3grs (3.71g). Starting with that data and reducing 5% or so you could safely work up from there. Hope this helps.
