So I'm giving this chrono ladder test stuff a try.
257 Wby (24"), IMR4350, 110AB, with a Magnetospeed
Going from 62.2 up to 64.0

3221
3288
3251
3297
3297
3310
3312
3258
3339
3350

A couple fell way off, no I didn't mix them up on accident. 63.2 gave the 3310 and 63.0 was the second 3297. From those, which would you try? Or just both?
