While I don’t doubt some of the velocities quoted, most tested data would lead me to think that any 250 grain load velocity above 2,600 fps or so is venturing into over pressures. Just because there is no sticky bolt lift, flattened primers, etc. doesn’t mean high pressures do not exist. I think to exhibit classic mechanical overpressure signs the load is probably in excess of 70,000 psi. I don’t recall any published data for 250 gr bullets exceeding 2,600 for a 22” barrel. Nosler shows a few loads above that but with a 26” test barrel.
