Thank you Kind Sir! I've read in several places how well data for the 7x57 and Sierra's will work for Nosler Partitions, etc. Makes a lot fo sense to work up loads with them, then, for grins, back off a tad and tweak the load to the Noslers. Of course, even at 2700-2800, either Sierra ( the 175SBT and the 160 GKHP) will work just fine on thick hogs or deer. I finally have both rifles ( my 7x57 & 338WM) all bedded, tweaked, scopes mounted, etc. I am planning on laying up some test loads now. When I finally do get to shoot again at the range, I will have several bullets/loads ready for some fun with the chrono/targets. I am "so tempted" to get some Woodleigh 175s, but this rifle is a complete "unknown" to me, it may hate the heavies. So, hey, prudence dictates to "wait" and see. But "IF" I can get an accurate, safe load with that 175SBT at "2700+ fps"!??? Wow, that's in good company with a 30-06, much less the standard .280. Even 2600fps will be a thumper. Merry Christmas Doc!

Doc...a lot of new data shows R26 being a great powder ( and it was in the few rifles I tried it in) but I remember you have had wonderful results in the .280 with N560? I finally gathered up a pound awhile back, and I'm thinking it may be "just as good" as R26 in the 7x57 (compared to the .280)? What's your opinion on this?

I have had good success with N560 in a variety of standard cartridges. I would be inclined to use whichever of the two was most available at the moment and yet gave me reasonable results.
You get slightly more velocity from RL26, if velocity is your goal. Either gives good case fill. Perhaps RL26 burns more completely if muzzle flash is a consideration. I don't see a strong reason not to use N560 if I had it.
