6.5 120 BT BC is .458, max velocity per Nosler (24” barrel) is 3068

7mm 120 BT BC is .417, max velocity per Nosler (26” barrel) is 3262, I get 3126 from a 22 7/16” barrel.

Do you find a difference of .041 to be significant?

6.5 140 BT BC is .509, max velocity per Nosler is 2731

7mm 140 BT is .485, max velocity per Nosler is 2953, I get 2890 from a 22 7/16” barrel.

Do you find a difference of .024 to be significant?

It would be interesting to run the numbers and verify the distance at which the better BC catches up with the faster bullet. I’ll bet it’s farther than you think.

Obey lawful commands. Video interactions. Hold bad cops accountable. Problem solved.
