Hiaring8,
I haven't loaded ELD's in my 7RM yet, but my standard load with all bullets from 154gns through 160 and 162gns is 69 grains of AR2217 ( H 1000), 215 primer in Norma brass, which clocks around 2900 f/sec from my 24" Bbl. Just filled the meat safe with a Fallow doe yesterday using a 160 NAB at 170 yds . . DRT, but wasted the fore quarters! Have worked-up to 70 grains with no adverse signs, but best accuracy was at 69gns. Very stable in all temps too.
Cheers, Jack
