Trijicon 5-20X50 help

I just returned from the range with my newly acquired Rem 700 xcr long range tactical chambered in 300 winmag. It sports a 5-20 trijicon, badger rings and a US optics 20 moa base. At 100 Yds the scope is mechanically bottomed out and the rounds are impacting 11 minutes high. The scope has 51 minutes of internal elevation adjustment Anyone else experience this with this scope. If so, simply put, how do I fix it.....personally I think buying a nightforce is the only option. But if I could make this optic work it would be great, its got incredibly clear glass. Is it possible to get this rifle to shoot out to a 1k yards with this optic and still have the ability to adjust for short range work? I keep trying to do the math but keep confusing myself. Any insight is appreciated.

UPDATE.......Figured it out, I've got everything all wrong. I was under the impression that I had a total of 25 moa of internal adj but I was way wrong. I don't know why i didn't catch it before. Must have gotten over excited about mounting up the scope(thats when I first counted the total internal adjustment). I spoke to Trijicon today and they straightened it out. Kinda had a moment. How could I possibly have a scope with 25 moa of adj when everyone reports at least 40?. So I re-counted the total elevation which ended up a total of 51 minutes. Now according to my calculations, if I am 11 minutes high at 100yds with a 20moa base, my POI will be 9 minutes low with a 0moa base. Dialing 9 minutes up will bring me to a 100 yd zero which leaves me with about 42 minutes of elevation before i max out. Should be plenty of adj for 1k yards according to my calculator. DUH! Thanks for the input guys.

Remove the 20 MOA base and go with one with no slant. Those scopes are okay for under 1K glass, not great but pretty okay.
I admit that I know just enough to be dangerous.....but dangerous at ever extending distances.

MOA bases, as good as the USO may be, are not always accurate and there can be differences in the action elevation causing error as well, possibly both. Try a zero or 10 MOA base and try to alianate the problem. These things can be frustrating I know.

I am using a EGW 20MOA base/w Burris XTR rings and have 12 MOA left at the bottom on mine. Something not adding up right. You may have received a wrong base or ring! This has happened to me before or should I say trefore Bill Maylor..

Re: Trijicon 5-20X50 help


how would you compare the glass to other high end glass? I'm curious, I looked through a trijicon 5-20 and thought it had really nice glass. Much better than Leupold. For my eyes I thought about as good as Zeiss Conquests. Have you looked through the Vortex viper pst glass?

Also, for the original poster. I'd remove the slanted base and try a 0 base. Or remount the scope after you zero or center up the adjustments.

Re: Trijicon 5-20X50 help

Probably not what you want to hear, but I had a Remington 700 SPS Tactical that I could not get zero'd at 100 at all. Totally out of adjustment windage and elevation.

I had to send the rifle back to Remington and all they did was bend the barrel and ship it back to me.

Never been happy with Remington since I started in long range shooting. YMMV.
