Thanks RR and Merry Christmas. I forgot to ask for a 62K psi max. But this gives me a place to start.

Ridgerunner665 · Dec 24, 2014

Edited to 62k psi...

8208 looks pretty similar to 4064. I have an excellent load using 4064 and 200 Hornadys. I've not found anything yet that's made me wanna change from RL15 for 225's and 250's.

IMR 4064 does work great in the when with 200grainers . I found IMR 8208XBR too be cleaner burning with a little more speed. They also claim temperature stability.Lee
