I'm having a heck of a time finding good data for this cartridge. I am especially interested in loads for the 260 Ballistic Tip.
I have AA2520, H4895, R15 on hand and have been thinking about picking up some varget. I understand AA2520 is the classic powder, same with the 6.5 JDJ, but recently with the JDJ folks have been saying that R15 and Varget are terrific. Problem is that the Hornady and Hodgden manuals, the one I have, don't list the faster powders with the 270 gr. bullets.
Any info is appreciated, Thanks!
