I heard the new Sniper load used RL15 & the reason that powder is so hard to find, but I have seen no proof of that at all, maybe they do use 4064.
I use 43.1 gr. of Varget and 178 A-Max in my 5R with vel. being 2615. I wonder if 4064 would yield faster velocity but with the same accuracy? Also, does 4064 vary more with temp. change than Varget?
