I always like reading people's test reports, and await the findings with those heavy .25s, but I fear Calhoun is right, for I remember him doing a fair bit of testing in that regard. Length matters, not length of bearing surface.

Any data regarding heavy bullet performance in the .250-3000 is almost meaningless without knowing the exact rate-of-twist in that particular gun as well as velocity (chrono'ed not guessed).
As stated earlier, there was a fair bit of variation in actual twist rates with earlier guns. You might get lucky and have a barrel that will spin those 117s enough to stabilize and yield good accuracy, and if so, get thee to the nearest Lottery agent for your luck is running hot. Personally I would save those heavies for something/someone else as it would be a shame to waste them on a wild goose chase, but that's me.
