Nighforce BR Scope

[HeavyVarmint]

I was wondering if the Nightforce BR 12-43x56 scope with a 20 MOA rail can will be able to reach 1000 yards with a 308 Win. Or, is the 8-32x56 a better choice.

Should do nicely, but depends on your speed and BC. Might be on the edge if you need 40-45MOA or more, but with a 155/167 Scenar at 2700 it should work out fine with a 35-38MOA drop.

Nightforce's webiste says it has 40moa of internal elevation for the Benchrest model 12-42x and with a 20moa rail you get 60moa... So if you consult JBM's ballistic software for your intended load and day you can see if looks okay to you. I would guess that 60MOA of adjustment are enough. But if you don't thin so then why not a 30moa scope rail? That would give you 70MOA of adjustment that should be more then enough. http://www.eskimo.com/~jbm/ballistics/traj_basic/traj_basic.html

Thanks for the help the 12-42x56 looks good and the calculated drop with a 175 gr. Berger VLD is 37.3 moa.

I have been using Burris Rings,20MOA inserts ) with the 20 MOA Base at 1,000 yds. - works fine. You can also reverse the inserts to negate the 20 MOA base and shoot at 100 yds. Happy Forth ,

CAUTION - The NF owner's manual instructions say do not use dovetail type mounts,i.e. Burris, Redfield,Leupold) on this scope. I assume there is a possibility of denting the scope tube, which I recently did on a Sightron using Signature insert type rings. There was a small burr down in the lower ring dovetail.

I am using a Badger Ordnance 20 MOA rail with Max-50 rings. I currently have a Leupold Mark 4 6.5-20x50 scope. The Max-50 rings are standard length and the scope is just about touching the barrel. What would be the best ring height for the Nightforce 56mm scope using Badger Ordnance Max-50 rings?

That isn't how it works...

The 20MOA just lets you put your 100yd zero near the bottom of the elev. travel and have near 40MOA up...

the 12-42 would be pushing the limits,especially on a crooked factory gun that may require windage to zero, losing you elev. travel)

I would go 8-32, because you will be almost topped out at 1K which is NOT GOOD for precision work...

Ideally for your -56mm scope you need about an inch.The max-50 Badger nearest is the 1.125" version,Part no 1005-306-13)
These are what I am using with my 12-42x56 nxs.The standard Badger rings are available in 1" height but if you want to stick with the max-50 you will prob need the 1.125.You can obviously try your existing rings, but dont think you will have the clearance . Hope this helps.

Thanks for the help everyone.

Well, you're correct I didn't explain it accuractely. All I meant was that the with the 20moa bases he would have 40 minutes of internal adjustment plus that of the base's adjustment in elevation. And I figured that 20moa would put his .308 on dead center at 100 yards. But that isn't necessarily true, 20moa might not put him dead center at 100 yards he might only 35moa of adjustment after 100yards. I should have explained that better as it does look like I added 20moa plus the 40moa of internal adjustment which is inaccurate all meant was that if 20moa was dead center at 100y he would have the full 40moa of internal adjust to reach out to 1000 yards.
