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. Info - AR -scope height is 1.47" - .223 Nosler partition 60 gr BC .228 - velocity 3160 700 scope height 2.5" .308 SMK 168 gr bthp bc - .447 vel - 2650 |

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 |
