Re: ior 3-18x and scope base
Dsparil,
Ok I'll bite:
IOR 3-18 FFP MIL adj. has a listed 75-80 MOA of adjustment or 22 mils.
IOR 3-18 SFP w/1/4" click adjustment has a listed 65 MOA of adjustment. Both of which is more than 50 MOA.
But if your 3-18 has only 50 MOA of adjustment, and you add a 20 MOA base, then you should have 45 MOA up and 5 MOA down.
Theoretically, 45 MOA should get most 308 rounds to 1000 yds. and then some. Being that 45 MOA @ 1000 yds is 450 inches.
Perhaps you were talking about another IOR scope like the 6-24x50mm, which has a listed 50 MOA of adjustment?
