Noob question - 20 moa rail

[migrant hunter]

This is my first attempt at a long range rifle. I bought a savage 10 TR and a cabelas 4-16 scope. The rifle came with a 20 moa rail. I shot it today for the first time and it's about a foot high at 100 yds, with the scope adjusted as low as it goes.
Do I need to just get a regular scope base, or is something wrong?

What did the person who sold that stuff to you say needed done? The ammo / bullet weight can make massive difference on impact point - did you try more than one kind of ammo? I do not know how the two ranges compare - is that close at 1000 yards (what you want), to be a foot high at 100 (what you got)?

20 moa bases are only really good for longer range. Most may not zero POA/POI at 100.

To zero at 100, you will need to install a different base, or you can get burris rings with inserts to cancel the moa base.

 

[Suther]

Depends on what your goal is. If you want to shoot at 100 then yeah might need a 0moa base, but that will limit how far out you can go with your current scope.

A zero moa base could get you to 500 yards before you run out of adjustment.

 

[Snider shooter]

To shoot dead on at a 100 your going to have to get another base or buy a scope with enough adjustment. If most of your shots are at shorter range that change the mount out being easiest.

OK, I think I've figured it out. I think my zero stop inside the turret can be moved to different positions. I'll load some more and try again.

I’ve got a 20moa rail on a rifle and had no issues zeroing at 100m.

Where on earth did you come up with this ridiculous notion? I have a half dozen rifles w 20 MOA bases and not one has ever had trouble zeroing at 100 yds. I mean MAYBE if you were using a 7/8" rimfire scope but then ......... why?

I run a 30moa and zero at 50y !

My scope has 15mrad of adjustment and I can dial out to 300 with it.


90% of people do not need any extra cant.

That's an incredibly hard statement to believe if your using any of the popular sub 500 scopes.

People throw around 20moa like it's a performance improvement over 0 moa like it's an octane rating.

Very few will need a 20 moa base as I believe most people hunt and plink at 300 yards or less

 

[Snider shooter]

Sounds like OP didn’t realize he had more adjustment in his scope.

Sounds right, EVERYBODY in our club that shoots Savages ( and any brand of rifle for that matter!)with 20MOA rails on them has absolutely no issues shooting at 100 yards, in fact the vast majority start there to build their dope charts for out to 1K.

I run a 30 moa rail, and an extra 30 moa cant in the rings. And I still have a 50 M zero. Just have to use the right optics.

Did this to maximize my ability to dial out. Granted this is on a 22 lr, so its just over 3 dial rotations to get there, but I still can, and it is fun shooting the 22lr out to 500m.

Again, just have to use the appropriate optics.

To 1000m I have never needed anything other than a base without included elevation.
I have used Burris rings with eccentric inserts to incorporate a bit more elevation.

I run a 50MOA base on my rimfires... 20MOA on centerfires.

To the OP, I was going to guess either the MOA rail was backwards or there was a zero stop in the scope. I guess depending on what Cabelas scope it is, I was assuming the 'Covenant' model which should have enough travel. Lots of PRS rimfire shooters in production use it as a budget scope.
