I'm currently load testing for my 300 RUM with 208 AMAX's. I've only tried H50BMG between 95gr and 99gr and I'm not having much luck. I'm thinking about trying H1000 and Retumbo since I've seen guys having luck with these powders but there's still not much info around for this cartridge with the 208/210gr bullets. I was considering trying some 210 VLD's but would rather stick with the AMAX's since I have quite a few already and I know if I mess around I will find a load to work for them. Here is my current load:
Nosler brass 1x fired
CCI 250 primers
H50BMG 95gr-99gr(99 is right at my pressure limit)
3004 fps with 97.5 gr
Hornady 208 AMAX
COAL 3.893 (I have a little more room to seat out further which I plan on doing as well)
Just wanna see what everybody else is using so I can find a better starting point. Thanks.
