    Picked up an vortex he 4x16x44 today for a good deal. I see it has 75 moa adjustments. I'm shooting an 7mm mag at 2880 with .617 bc . Right now I'm out to 500 yard with mildots. But I'm wanting to dial. Will I need a 20 moa base out to 800 or 1000? 800 will probably be about my max but eventually I'd like to get out to 1000. But thats another topic;)

    Thumper1991,

    With your set up at an altitude of about 5000 ft Elev. you should be able to shoot
    at around close to 1200 yards just using the turrets and without using a tapered
    base.

    With a 20° base you should be close to 1500 yards.

    Thank you for your reply. I do usually shoot around 5000 ft. And hunt 5 to 7500. Thanks again. My program just didn't seem right. But you confirmed what the strelok was giving me.

    I have the same scope, also on a 7 rm, and mounted on a 20 moa warne tactical base At 1000 with a 300 yd zero your load should be dropping just over 21 moa. that is well within the range of the scope, so you dont really need the 20 moa base, but it will come in handy if you ever want to go farther. my setup gives me about 56.5 moa of adjustment past my zero. theoreticaly (i've never shot past 1000 yet) that should be enough to get out to about 1650yds.

    No you don't need it. I use Zero MOA EGW HD bases on most of my rifles and they work great. Len sells them and the TPS TSRW rings that I use through the LRH store.gun)

    I have a Vortex HS long range 4-16x44, the same caliber rifle and it sounds like we are shooting the same bullet. I do have 20 moa bases but I can shoot to 1200 yards at 2600 foot altitude with only 25 minutes of elevation. You should be fine out quit a bit further than that.
