80 MOA Base ??????

Hello all, it's been a while since Iíve posted a long range question. So here we go. I have recently purchased a SWFA S.S. scope. With this scope I purchased a 20 MOA base to mount it to. Oh by the way Iíve mounted this on my 3oo Weatherby. Once I had everything mounted I discovered I still have another 65 MOA of adjustment down. So I started thinking why wouldn't want to utilize the total amount of adjustment possible from my scope? After zeroing my scope at 100 (sitting on the 20 moa base) I had 65 moa of adjustment down and 75 moa of adjustment up, that is a total of 140 moa of adjustment. So my thought was if I could find an 80 MOA base that would give me almost the full swing of adjustment for shooting longer distances. I started searching the internet for this beast and have had no luck what so ever. Has anyone out there tried this out or am I going on a wild goose chase? And or do you know where to purchase one? I ultimately would like to use the max ability of my scope to reach out as far as possible. Any guidance, theory, help or suggestions please I am open for all direction.

200 MOA of vertical adjustment ...

different approach

I emailed them and if I remember right they would make a 60 moa base as needed.

Re: 80 MOA Base ??????

For applications like that I use a Variable Gantry Mount.

I have used them on my .22lr to shoot out to 500 yards alot, and even out past 700 just playing around. But mostly 500 yards

The way they come there is 5 settings, that can be adjusted from anywhere 0 moa to 100 moa. and thats just in the base! and can be slightly modified for around 400 moa of adjustment.

Here is a video I did explaining it


and a video shooting with it


If you would like more info, Shoot me a PM. I have a few kicking around.

Ideally, you want the scope in or near the center of the turret range at the most used distance.

As scopes get near the end of there adjustments they are not as precision when making MOA adjustments.

If you only hunt/shoot 2 or 300 yards a zero Moa base is best. At 600 to 1000 yards a 10 to 20
MOA base works best if you shoot only 1000 yards you may want a 25 to 30 MOA base, but you may not be able to get a 100 or 200 yard zero.

Just my opinion

Drbill and Clayne b, both of the scope mounts that you have posted are awesome. I have never seen such a thing and am impressed. But I love doing the mill dot math also. So Iím still looking for a solid rail with a large moa rake (if possible). If I have no luck finding one at least I know I can get one of these mounts to do the trick.
JE custom, I understand about the accuracy going south the closer you get to the bottom of the adjustment of the turret. I learned this the hard way. But as I stated before I am on a 20 moa base now and zeroed at 100 and still have another 65 moa of adjustment down. So maybe not an 80 moa but maybe something close to that. I really would like to utilize as much of the turret as possible. I haven't seen anything past a 30 moa and was just wondering if there even were such rails out there. I love all of your guys input into my questions and issues. Bear with my ignorance while Iím trying to get the biggest bang for my buck but I was even contemplating throwing a shim under the rear of my base just to see if I can get the adjustments Iím looking for. Not shoot it like this, but just a test to see if I can get the adjustment out of the scope and satisfy my curiosity.

Clayne B, those are some nice looking rings. I noticed the write up says they have an insert that grabs the scope tighter. What else do they do to help with moa? Once again excuse my ignorance. LOL
