Thread: 300 wsm long range target and hunting pills

Has anyone used the 212 gr ELD X in there 300 WSM. Beeman's son is getting one in Rem 700 soon ( on order) and is keen to use this bullet. Any suggestions for powder etc.
He is also thinking of the extended mag box so he can mag feed. What would be an expected velocity with this load/ bullet combo?
I have heard R 26 and 17 are good but 26 is hard to get at the moment, AR 2213 SC sounds ok so was thinking maybe Superformance would be good as it's not as bulky so shouldn't be as compressed as some powders.
