Do you adjust your zero when traveling?

[Alaska Bowman]

I recently moved to sea level but hunt in the mountains between 8-12k Elevation. If I sight in my rifles here, get all my dope in my Sig 5k, MV Temp table, chrono speed, etc. When I travel do I need to bring a chrono and get my new speeds and re-zero or just trust the rangefinder and check my zero against the readout based on the new density altitude adjustment? Meaning when I go check my scope at altitude, if I range it and my sig tells me it'll be 1.5" High at 100 and it hits 1.5" high, that im good to go.

Muzzle velocity and a 100 yard zero will be the same at sea level vs at elevation.

A 200 yard zero or 300 yard zero is far enough for a big elevation change to require rezeroing and I would strongly recommend a 100 yard zero partly for this reason.

Use 4DOF and Gun Angle, then adjust for local conditions once you get there.

This. Zero at 100 and go forth hunting at any altitude. Corrections at distance will change a bit based on DA.

Thanks for the feedback! IDK why I was thinking the MV would change with altitude.... appreciate yall setting me straight! More of a bow guy, lol

Depends on what scope you have......

I think it is more important to check your zero in case of the rifle getting knocked around during transit. I usually sight in 2 inches high at 100 at home before leaving on my trip (live at sea level). I always confirm zero after my trip up to Chama, shooting the day before the hunt. At 100 yards, the rifle is still shooting 2 inches high, no correction needed and this is at about 7900 feet.
