For reference, with at 350 gr FPB, the folks at blackhorn indicate around 1700 fps at the muzzle. That will give over 1000 FPE at 200 yds, probably near 1000 FPE at 250.

If you're shooting a 250 gr bullet, If one shoots more accurately than the other, I'd go with the one that shoots the best. At longer ranges, I value accuracy over a small difference in FPE.
