I have my scope (on AR) zeroed for a .223 Nosler 60gr at 50 yards.  -


I am going to place this scope and mount on a Remington 700 - .308 and shoot this weekend.


I've searched around without any luck trying to find a ballistic program that would allow me to enter in the AR zero/round info and then enter the .308 data and be able see both trajectories on a graph.





Can anyone suggest a program to look for? Or, if anyone has a few minutes, would you mind punching it up?





I am ultimately trying to find what range the .308 will be zeroed at when the scope is set at a 50yrd zero for the .223.





I feel like this should be pretty easy but for some reason, it's just getting lost on me. I'd appreciate any help/info I can get.

It's not going to work

Your zero is going to be lost when you swap the mount/bases/rings. This also doesnt account for differences in  scope height over the bore, cheek weld and rifle contruction.

Even hot swapping a one piece mount like a LT or Bobro you're still not going to get it right. You will have to re zero

I'm not very smart on precision stuff, but I think your best bet is to get a good repeatable mount and zero for each weapon. Then just write down the zero settings for each and go that route.

This. I do this for a scope I swap between 5.56 and 6.8.

Nikon Spot On, I use it for a lot of shit.
