Rifle Scopes Zeroing 1 scope on a rifle with a switchbarrel questions

[sasquatch98226]

My google-fu sucks, and I can’t seem to find an answer to this question, and I know it must have been asked before. So can anyone either answer the question or post a link to the answer?

I have a AI-AT with both .308, and 6.5 creed barrels. I plan to shoot comps with the 6.5 and the practice and shoot .308 matches with the other barrel. Since I am switching barrels and not the scope, do I zero for the faster bullet and dial “down” for the .308 and keep track of the changes, or vice versa? Or do I just zero the 6.5 and then change the info in the kestrel using the offset feature?

It’s really whatever you feel like doing. I just note my offsets and slip my turrets to zero. That way I don’t get confused when doing both holding and dialing on a stage.
If one barrel is only for matches and you just wanted to use the kestrel offset feature then I’d have the main zero as my comp barrel

I was listening to the everyday sniper podcast and Frank and Mike recommended to set your zero stop for the slowest ammo you plan to shoot then dial up for everything else.

I swap barrels on a Bighorn TL3 with an ARC Barloc and they are usually only a few clicks away in any direction.

I see no other easy way of doing this and would do it as you do.

Another way could be zero for the ammunition you use the most, have an offset zero for elevation built into your charts/device, then zero the windage for each load and just hold for wind.

Id say zeroing turrets would be the best way, but all ways can induce error if you make a cock up and forget where and what you are currently zeroed for.
