40 MOA base still zero at 100 yds?

[shooter981]

I'm building a 338 Edge on a Rem. 700 action with a 32" barrel. I have a Leupold 30 MM Long Range scope to install when its done. I was wondering
if I could still zero at 100 yards with a 40 MOA tapered scope base or would that be too much? If so, what do you think it would zero at with that base, ballpark figure? Thanks for any info.

I think your scope has 72 moa total, (thats what my 8.5x25 Lupy had) so in a perfect world you will have 36 moa each direction. We just put a 5.5 x22 x56 NXS on our 300 Win using a 40 Moa base and 1.125" NF rings. The NXS has 100 MOA of adjustment and zeroed at 100 yds. we are 10 moa off the bottom. I would say the best you could hope for would be a 300 yard zero. Which really would not be all that bad. Depending on what you are hunting, if it is 300 or closer, just shoot it. But you could be 4" high at 100. And again that is if the scope does have 72 moa, and the reticle is centered, and the base is a true 40 moa. in a perfect world.

Thanks for the great info! Yes, your right, 72moa on the Leupold.

If you can get 30 moa out of your scope and go with a 20 moa base that will give you 50 moa. With a 300 SMK @ 2850 Muzzle Vel. that should get you out to 1500 or a bit more with a 100 yrd zero.

I have used a few 40moa base on 308 setups w/ a 100yd zero.

Just another data point. I have a 40 MOA NF base on my 338 Lapua with a NF 3.5-15, which has 110MOA of total elevation travel. I can zero at 100 and have 92 MOA of up travel available. I believe the Mark 4 LRT 16x40 (the one with the real tall M1 knob) has 140 MOA total travel.
