the problem I had using an adjustable mount was sight height .the one I had added an inch . the mount raised my scope so high I didn't have a cheek weld , so I added another cheek piece . it got ridicules looking , and hard to shoot .
what I did was bedded my rail to add moa so I could use everything the scope has . depending on conditions I can dial 2000 yards , past this I use the reticle . I need to get a scope with more internal elevation .
I agree with the Burris rings with the inserts as probably being your easiest , cheapest , best way to go . after shooting a while you can decide if buying a scope is something you want to do .

What about reaching out to Cameron Murphy and having him make you a 40 MOA base for your Defiance? Then you can still use the Burris rings for any additional elevation you may need.

Another vote for the Burris XTR rings. As has been stated, you can get 40 moa out of them if you put 20 on each ring.
I use them even when I don't need to add elevation. The live center design easily cures a lot of mounting evils, and the composite material grips a scope tube exceedingly well without damage.

Thanks again everyone. I ordered a set of the Burris XTR Signature Rings to give them a try.(for now)
Just for giggles, I ran the turret up from my zero, I have about 38 moa left to dail up. Then I ran it all the way down from my zero and got 21.250 till it bottoms out. That's 59 moa total travel. I know I don't want to dail windage at the very top or bottom. So I'm guessing that the 40moa travel advertised is to allow for windage adjustments without damage to the scopes internals.
Man...I got to say...Taylorbok has this stuff figured out. Or he's been looking at my dope notes...lol
I really need to get my AB calibered. It says I need 20.125 dail up at 1000yrd, really it's 18.625moa. So if I'm at 21.250 from the bottoming out, with a 1000yrd zero, I should be 2.625moa from the bottom. Leaving 56.375moa of elevation I can dail. Plus the 10ish moa of reticle at 40× for hold over, if I need it. Does this sound right?

I've got a 300 RUM I shoot also

Get the Burris XTR rings, run -20 on the front and +20 on the rear. I dial my scope all the way down. Hang 50" of paper, shoot at the top. Measure impacts. I do this at 100yds. The will give you how much you need to add in the rings. I run this on 6 rifles.
If he does this his bullets will go over the top of the paper

If my dope is 18.625 at 1000yrd, with a 100yrd zero with the set up I have now. Can't I do a tall target type test at 100.
Hang a tall cardboard target with a aim point and a poi point that's 18.625moa above the aim point. Would I need to multiple 18.625 by 1.047 to convert to inchs to be more accurate on my poi?

That is correct. If you put those rings on with 40 moa cant your POI will be above your point of aim.
Do a tall target test like you said and measure poi offset and enter it into your calculator

As Taylorbok stated do your tall target test - and just measure the offset, you should not have to do any math or conversions just enter the measurement into your program after its in then fire up a test or mock shoot in your balistics program and see if it is telling you that you have aim below the aim point now at the 100 yard mark then you know you're set.
