Looking at Vortex Viper PST FFP with MRAD

How many Mils would it take to get to 800 yards with a 308?I am trying to figure out if I will be able to use holdover with a Mil reticle up to 8 mils to get me out to 800 yards +- I understand MOA ALOT better than Mils but Mils seem more precise except when it comes to holdover. The only reason I am preferring the MRAD over the MOA reticle is because of the 1/2 mil hash marks. If the MOA reticle had the half MOA hashmarks or went in 1 MOA increments I would be ALLLLLL over that scope instead

    The PST 4-16 has 21 mils of adjustment. Based on a 0 moa base, you "should" be zeroed around the center of the adjustment range. That "should" leave you with 10.5 mils adjustment.

    1 mil = 3.6 moa

    3.6 moa x 10.5 = 37.8 moa

    How many MOA to reach a grand for your rifle?

    The scope will be sufficient if you buy a 20moa base.

    Now, if you are going mil/mil ffp, do exactly as I was told. STOP THINKING IN MOA.

    Does that help?

    Thank you for the info, If I can get to 800 yds I will be perfectly happy, now with that being said, could I use the reticle subtensions and the turret to make up the difference to get to 800 maybe more?

    Absolutely you can use the substentions (hold-over) and Elev adjustment to get it done. Another note, with Mil turret adjustments data documented, you will have your exact hold-overs as well on the Mil hashmark substentions. Just remember that in 2nd focal plane scopes, your power setting will affect hold-overs, it will not affect the center crosshair. This can be a plus as well depending on your needs.

    If you decide to get a PST why don't you get one with MOA / MOA and pay an extra $100 for a Vortex custom turret? I did with mine and it is spot on out to 900 yds. No need for hold over. Range with your RF turn turret to yards and hold for wind and shoot.
