Home Forums Hunting & Shooting Hunting Optics Scope mounting Problem

I think I have 3 different sighting tools I can get my hands on. Bushnell grid, cartridge laser, Bore laser.

I have found the good old Bushnell grid with the different spud for each caliber does a great job.

NEVER try to figure out which way to turn the adjustment. It's written right on the adjustment knobs of the scope.

Which ever way the arrow points is the direction the bullet will go.

but it sounds like you do have a defective scope.

put the 20moa mount in the spare parts box

I go through there as well. I travel up 331 and take 55 out of Florala up to 65 then into Greenville.

Maybe a 10 MOA base?

Sounds like the 20 MOA was backwards.
Something isn't adding up.

I think you are adjusting things backwards. If your crosshair is low on the target looking through the bore, you need to adjust the erectors in the “down arrow direction”. This actually “raises” the crosshair in relation to,the target.

Yep. If that scope has 60 moa of vertical adjustment range then that's 30 up and 30 down from center. It follows that a 20 moa base would shift that to 50 up and 10; down available remaining.

Tipping the scope down will raise the bore.

Yes Sir - That is exactly what I did and I run out of adjustment before the crosshairs come up to the bullseye.
I might also add that the original 20 MOA base came installed by the manufacturer, and the highest end was mounted aft.
The 0 MOA base, that I added, is mounted exactly the same, with the same end aft.
Again, under the caps it says "1/4 MOA", and from stop to stop is 120 clicks. So, I conclude the 60 clicks = half way. or equal up/down. My understanding is that "1/4 MOA" is 1/4" @ 100 yds, so 4 clicks=1.047", or for simplicity 1". At 50 yds this would be 8 clicks=1". If I am correct, then if the crosshairs are 9" below the Bullseye @ 50 yds would require 9 x 8=72 clicks!! Only have 60, and I am running out of adjustment. Might have to trade the Crown Royal in for some 101 proof Wild Turkey....

Reset the zero stop. That is probably all that is wrong. I just went through the same thing. Take the two allen set screws loose on the elevation turrent and turn the turrent counterclockwise 1/2 turn. this should give you enough elevation downward to make it work.

That would make sense. I looked at the manual on the Burris site and the process is explained on pages 2-3.

The specs say 64 MOA total elevation adjustment. So, from center 32 MOA up and 32 down.
128 clicks each way from center and 256 total.

If you use the 20 MOA base and everything is centered, you will then have 52 MOA up available and 12 MOA down available

Looks like the zero stop is limiting your adjustment range. Easy fix with the supplied wrench and owner's manual

Ah!!! Without having to break out the Crown Royal, Wild Turkey or the Jack Daniels - Resetting the zero stop did the trick!!! After 15 rounds total through the new rifle I'm at the 200 yd marker (target) and this rifle is tacking - The last 3 rounds group measure .63" @ 200 yds (measured with caliper). Not bad for an old fart!! Thank all of you for your comments and suggestions - A great group.

So you can teach an old dog new tricks. Glad it worked out.

Older hunters (and I’m no youngster!) and new scopes = fantastic comedy!

Glad you figured it out and thanks for the chuckle.

Reminds me of my uncle. On a recent hunt where his only shot options were all 250+ he was frustrated. Traditional .270 and 3x9. I tried getting him set up to shoot and he just thought 300 was too far. I put him behind one of my set ups and talked him through a few shots at 2x+ that distance so he just had to have one. Unbeknownst to me, he walked into his local Sportsmans Warehouse and came back with a vx5 something or other/CDS. When I tried to politely explain the shortcomings of CDS vs an MOA turret, proper zero, ballistic changes due to environmentals, etc., he just asked for the Jack Daniels.

A little late now but I always use the mirror trick to start out with the reticle centered vs counting clicks. Put the objective end of the scope on a mirror and look at the reflected image. You can move the elevation and windage knobs until there is one set of centered crosshairs reflected. This gets you started with the adjustments centered up.

And then what do you do? Do you use mounts that allow windage/elevation adjustment so you can do as much bore sighting as possible with the mounts before touching the turrets?

I was sent a 20 moa by mistake from Midway. I had same problem as you . I made a shim for front end of base. Worked ok.
