Ran out of elevation what now?
Ok so I got a B square scope mount for Christmas for my 222 mounted my redfield revolution on went to sight in and ran out of elevation so what now? Should I use the scope rings that came with the B square base should I put the original rings that I had on the scope back on? I'm puzzled I started at 25yards just to get on paper

shims
Never had to use them, but these might be in the works for you. Just google scope shims and see what comes up; a possible start for you on your dilemma. The site mentioned here might/could get you started.

Are you sure you mounted things correctly?

+1 on the mounting. Try switching the rings. On some mounts, there is a difference between the front and rear ring.

If rings came with the base, they'll be a matched set. Use 'em. As it is now, your scope is not mounted correctly. One end is higher than the other.
You'll also have to bore sight. That can be as easy as looking though the barrel(need good eyes to see though a .22 barrel though.) at something about 100 yards away. (Street lights are good for that, but pay attention to who and what's near 'em. You don't want to be explaining why you're pointing a rifle out the window.) Anyway, look through the barrel, line the vertical cross hair up on something you know is square, and adjust the reticle to be on the light or whatever. Should get you on paper but you'll still have to sight in. Whole thing is best done with a bore sighter with the rifle in a padded vise.

Did you first center the crosshairs of the scope before mounting? They don't always come perfectly centered. You can runtime adjustment all the way to one side, then count the clicks or turns if no clicks to the other side, then back off half way. I prefer using a mirror. Lay the mirror flat on a table under a fairly bright light. Place the scope's objective lens on the mirror, look through the scope and adjust the hairs to coincide with one another. Sound difficult but is quite easy. If your alleviation hair was already too far from center it just might make the difference. Checking the mounts would be the next thing I'd do.

Shoot standing up.
But seriously, mounting scopes is somewhat more complicated than folks think. So is using them, come to think. It would help to do a web and forum search on the subject. There's too much about it to describe here in just a few words.

Center cross hairs in scope first.
Shim Guide http://bushnell.com/getmedia/43d8a20...2.pdf?ext=.pdf
If you cant shim the base, shim in the rings, under the scope. Cut some soda cans for shim stock. |

Good one, Doyle. Very accurate shims can be made from feeler gauges, too.

You can get brass shim stock in various thicknesses from almost any auto parts store. I have had great luck using it to shim mounts.

Where exactly do I put the shims at? In the scope rings or under the scope rings?

Put the shim under the base that needs raising. You may need longer screws depending on how much shim material is necessary. As suggested earlier, make sure the scope adjustments are centered, then use bore sighting to tell you when you are using the right amount of shim material.

Had the same issue once, a 20 moa rail resolved the problem perfectly.

If you ran out of elevation at 100 yards then, I might consider sell, return or trade the gun. Or,
As already suggested, if available for you rifle, mount a 20 moa base. That will give you 20 inches elevation at 100 yards. And a good flexable platform to any cross slot (weaver style) mount rings. Also, switching to a quality scope (Leupold) can easily double your range of elevation. I had this problem once, and went from Bushnell to Leupold and problem solved. Yes, I wanted to keep the gun. Last but easiest, you can use Burris signature rings that can be purchased with plastic inserts with various offset. You can get 20 moa, simply insatlling with the appropriate insert. These rings do a good job of protecting the scope from any marks. These rings can be combined with the 20moa base to allow much longer range zero (or dial up). http://www.burrisoptics.com/signature-rings You could damage a scope with shims. The scope tube does not like to get bent. I dont know what a B-square mount is. That sounds like AR talk? Or what is the gun? |

Oh yea, You need to be 1 to 2 inch LOW at 25 yards. Again, so little information...
