Rifle Scopes Can I sight zero at 100 with this setup??

[Renner22]

Hi, new owner of a Remington 700 SPS AAC-SD 308 20" heavy barrel, and about to mount a Nikon M-308 scope, w the BDC 800 reticle.

I would like some help on whether to mount the scope on standard weaver bases (2 piece) or the Nightforce 2-piece bases with a 20 MOA slope built in (I have both).

The Nikon scope comes with a 20 MOA one piece rail and rings, which I'm not using because the solid rail limits access to the top of the receiver (not using a DBM).

So, my presumption is that Nikon thinks 20 MOA is the right setup for that scope and its intended purpose ( ranges out to 800 yds), but I've heard that sighting in this scope with a 20 MOA base at 100 yds is difficult.

I am using Leopold PRW medium rings, for a one inch tube. The Nikon scope has a 42mm objective and is 13.5" long.

2 important factors are:

1) the range I shoot at has a 100 and 200 yd range. I will be using the rifle for some hunting (up to 200 yds), but mostly target shooting and would really like to test myself out to 800 yds+.

2) the Nikon scope has 40 MOA "listed" adjustability, but I got 220 clicks range, which is 55 MOA actual. Theoretically this is enough range to get me to zero with a 20 MOA, but I just don't know how much adjustment I need for the ring and base setup that I want to use.

Has anyone had experience with a similar setup, and whether or not they were able to get zero at 100 yds with the 20 MOA base with this scope? Thanks!

Anyone? Bueller? Any Nikon experts out there?

You should be fine with the 20 moa base and a 100 yard zero. You could have a problem getting to 800yds+ with the zero moa base.

Mount it up and go shoot.

Not using that scope, but I have the same action and barrel. Using a one piece weaver 20 moa rail, and a cheap 1" tube 10x bushy, I had no problems. I'm surprised you can't top load with that rail though.

Great, thanks. I'll mount it on the 20 MOA base this week and start there.

BTW, I can top load and unload, but its narrow and I've got big hands... So going with 2 piece is more of a convenience thing.

Any thoughts on whether I can go with low rings? (I bought medium). My suppressors not in yet (still in line to get a tax stamp), concerned that the can might block some of the view... Also worried about the bolt.

the nightforce bases are taller than the weaver ones.

Low rings should be good with the 42mm objective. Mount it up with what you have and go from there. Should only take a couple minutes to set everything up finger tight to check clearance. Once you know clearance is gtg, reassemble and torque it down.
