I have (3) 7mmRM rifles with 26" barrels and (1) 7mmRM with a 23.375" barrel.

I have shot (8) deer with a 22" 270.

If shorter barrels are lighter and more accurate, but longer barrels have more velocity, I would take shorter. Still, I have never cut length off a barrel yet to make it shorter and more accurate. Enough get short cutting off shot out throats or the wrong chamber or the wrong threads.
