Howdy Everyone!
Soon I need to develop a tastey Elk load for this fall. Can any of you let me know your most accurate load for 200 gr Nosler Partitions under Retumbo for 300 wm? Many thanks!

I have gotten good results with 79gr of Retumbo, 215 primers, Nosler brass, .025" pff the lands. I would work up from a couple grs less powder. I get 2925FPS out of a 24" barrel, sub.5MOA accuracy. I get the similar results with Berger 210's and Nosler 210 LRAB's.
