Loosing mil elevation, need help!

[Leadfarming08]

Hey gues I’m new to the site. Looking for some advise on a set up I’m working with.
Rem 700 308, vortex diamondback tactical 50mm/30mm tube, vortex mediumpro rings on stock two piece base.

scope should have roughly 19 mils of total travel (elevation). Well, at a 150y zero, I am only accessing 6.8 in the positive elevation and 12.2 negative

obviously it matches the 19 total mils but I feel as if I’m missing some mils with my zero. why and/or where should I check to make sure it’s not user error. I would think a 100-200y zero would be closer to 1/2 of total elevation (9.5 ish)

set up has punched steel out to 750y so it’s set up OKAY. TIA!

If you want more elevation toss a 20 MOA scope base on your rifle.

Your scope sits above the bore. Because of this you lose a little bit of up elevation zeroing your rifle. Because your scope is mounted parallel to your bore you’ll have less up travel than down travel. Exactly how much that is depends on the individual rifle and how high the scope is mounted.

if you do as suggested and get a 20moa base you should get almost 6mil more up travel than you currently have.

it’s also a good idea to zero at 100. Doing this all your Adjustments will be up.

Great answer thank you luvman! I will look into the 20moa base.

Is punching steel at those ranges your main purpose with the rifle? If so, 20moa base will do the trick for you, but bear in mind, you won't be able to zero your rifle at 100 or maybe even 200 metres, and you will actually have to hold under targets at those ranges to hit them. Just something to be aware of.

The guy has a total of 19 mils of elevation travel. You have no idea what you're talking about.

My bad, should have read more carefully, just speaking from my own experience, I have shot 3 rifles with 20moa rails and have not been able to dial the scopes far enough to zero that close, am I doing something wrong?

Possibly. Tell us more about the rifles and scopes.

For reference my rifle has a 20moa base and my scope mount has 20moa of cant. I have no problem zeroing at 100yds with 40moa of cant.

A 20moa base should case no issue with a 100yd zero as long as the scope has 50moa or more of total internal travel.

Just spitballing here... Is it possible the canted base is mounted backwards?

I agree a 100-yard zero should be easy with room to spare, even with a 20 MOA base.

19 mil of travel = 65 MOA. Should be plenty.

Did you mount them backwards? Are you bottoming our or just hitting a zero stop? 20MOA mounts shouldn’t stop you from zeroing at 100 and I’ve never had or seen it happen to anything I’ve used or assembled. Probably just a simple mounting mistake.

OP,
Get a 20MOA base and zero at 100. Trust us, you’ll be much happier.

You could have a bad seal on the scope somewhere and the MILs are leaking out.

No, but really a correctly installed 20 MOA base/rail would fix you up.

Yes, you’re doing something wrong.

Rails definitely weren't backwards, they were integral lol. Rifles were a RPR in .308, Rem 700P in .300 Win Mag and Lithgow LA105 Woomera in 6.5 Creedmoor. Scopes were a Burris XTR II 3-15x50 with 34mm tube and a Leupold vx3i lrp 8.5-25x50 with a 30mm tube. All on 20 moa rails with no further cant in the rings. When you put it that way I agree there should be enough internal adjustment. Would the zero stop be locking out half the adjustment from the factory? I never messed with it on either of them.

You just answered your own question.
