Whatever you do if you use RL 26 buy a bunch of the same lot---if you can find it. Worked up a load fro my 6.5 PRC and the next lot blew a primer and rocketed the 143 ELDX at 3170 fps!!!! The previous lot was giving me 3030 fps and under 1/2" at 100 yards. Lot to lot variation is terrible at least in my experience. I went back to RL 25.
