jrh84, all I'll say if you intend to use RE-15 for Palma is: don't. lol! In my experience, it gets pretty high on pressure before you really get the speed you want/need for 1,000 yards. By high, I mean blowing virgin primer pockets on the first firing. I never tried to run it with 90's, but it's not that well suited to that weight anyway.
Truthfully, I don't know that there ARE any significant advantages to RE-15 over Varget. I just chose RE-15 at the beginning of time because it is a cleaner powder. Except for the last 8 month's use of a triple base powder for LR Service loads, literally EVERYthing I have done, won, or lost, was done with RE-15. It's never left me wanting, and after the reformulation to reduce it's temperature sensitivity, it doesn't want for much of anything.
But I could have done the same with Varget.
BOTH of their loads will fall between 23.5 and 24.5 grains, depending on the rifle. Truly, I do not have loads for Varget, but I THINK the guys are running more like 23.5-23.8 Varget, where they are 24.0-24.5 RE-15. But what do I know?
For this guy, it will really depend on how the AR reacts to it. Find the load for the AR, and then see if it will also shoot in the bolt rifle...it probably will, and it is very likely to fall in the "known range".
But you'll like RE-15. Clean-ish, carbon on the BCG etc. doesn't build up that fast, and doesn't seem like hard-rock-carbon-mountain when it does.
