Just my opinion

You aren't planning to be a PRS competitor right? You just want an optic you can learn to shoot your 308 at 600 yrds and eventually to 1000?

Age old arguments on all the shooting forums.. mil vs moa front focal plane vs second focal plane

Lets look at who uses what

Mil-FFP the military, the tactical crowd and competitor's who need rapid range estimates

MOA-SFP target shooters and most hunters

I say pick the one you are most comfortable with. Both work just fine. Lots of.strong opinions out there. Don't let them decide for you

Lots of.good scopes out there. Lots of junk too. And a few exceptional ones. I am old and need all the.magnification i can get. When i was 20 a 10X was all i needed. Now my target scopes top magnification is in the 40 to 60 power. All depends on what you pocketbook can stand. I would not pick something with less than a top magnification of 24X.

Low end vortex PRS or Luepold 3i and up from there
