I just built a switch lug barrel gun with the following barrels:
  • 24” 6.5 Creedmoor
  • 16” .308
  • 22” .223
So, my question is which barrel should I zero the scope on and then dial the windage for the other two? If it helps, The scope on the gun is an ultrashort with an H59 reticle
 
That's a personal question really. I would rezero at barrel change. Zeroing a scope is pretty quick. Changing barrels takes longer IMHO.

Which ever you shoot the most???
 
If you only want to run one zero then zero to the barrel with the lowest impact that way you can dial to the other barrels zero and still run a zero stop.

so many zeros!
o_O

this was exactly what I was trying to figure out - which barrel to set the zero stop on. I guess I need to see which is the flattest shooting at 100 (guessing the 6.5) and then set the zero stop there and dial up for the other 2 (and Save that to Strelok or take some pics with Ballistic-X of the adjustments and save them)
