Took the 3x9 off my 10/22. Shot fine. I replaced it with a Bushnell 3200 6-18x50. Now even with full elevation I'm about 2" low at 25m.

Any simple fix or do I need to drop $100 on Burris rings and inserts to correct this?
 
I'm no expert but with a large piece of glass like that I think the Paralax may not let you adjust for such a close target.

I think most large scopes are set for at least 100m and rimfire scopes are set at 25m or 50m.
 
I'm assuming that the 6-18x50 is an AO, and parallax adjustable. The 50mm objective is a big lens, so you probably changed to "high" mounts right? If so, its possible that you did run out of evelvation. Or your cheekweld has changed on the stock?

Burris Sig or Sig.Zees are probably your fix.
 
Dude, shim stock is cheap cheap, find someone in the biz and build it up. .010 at a base will show big at 100 yds. Remember your scope adjustments are just for fine tuning. Even a cheapy scope will work o.k. if it's centered.

I'm still using the medium rings I had with the 40mm scope on previous. Cheek weld seems the same.

Before you start shimming or change to new mounts, have you tried remounting the old rings and the new scope? Simple/cheap thing first. It could just be an installation problem, something may not be square/plumb. Reset everything and start over. Also, make sure that the scope is level with the bore.

Where's Reg when you need him? :lol:
 
With a boresighter on the scope looks perfect. I'm assuming it has something to do with the AO at close range (although the AO goes down to 10m).
 
Have you tried reversing the rings? Swap front & rear rings.

Sometimes this works.

You should also check that there is no "bump" on the top of the receiver. Some 10/22's have this problem. Its easy to check with a straight edge; with the scope base removed make sure no light is showing between the edge & top of the receiver.

Its easy to fix if encountered. Simply draw file the area until the surface is level.

Rod. :wink:
 
Put some 20 thou shim stock under the base and everything is good to go.

I need taller rings with that 50mm objective though.

I'm with this one as well....I put a scope on my gal's 22....ran out of elevation and windage....pulled it off,reset everything,tried it again.....the final time,I pulled the rings off and swapped them around...worked out great....just my experience anyway,but worth a little look-see anyway
 
I had the same problem with a new 10-22 I just got.
I shimmed the back end of the base with 2 pieces of old credit card.
The scope I mounted was a Leupold 2x7.
Cheap fix
 
I have a bushnell 6-24x40mm on mine , and I ran out of elivation as well , I used some peices of beer can and shimmed the rear underneath the base and that solved the problem
 
Did you take a close look at the front of the scope?

I suspect you checked the obvious, but with the 50mm objective lens and the medium rings is the front bell touching the top of the barrel or rear sight?

If so your scope will not be parallel with your barrel.
 
i had a banner 6-18x40 that had the same problem - out of elevation and still 2 inches low at 50- turned out to be both the mounts and the rail that ruger supplies- the scope comes with rings, so i used those, and it was the stock ruger rail- it's a strict factory anyway, so i went back to cheap 22 scope small obj and stuck the banner on the ar15 -maybe try a weaver rail as well- that's the way my brother went and he has no problems
 
I had the same problem with a high powered air rifle. At 20 yards and full elevation I still couldn't get to the X. Being an airgunner I looked in that world to find my solution, which because of the pellet's trajectory is quite common. I ended up buying a riser with an elevation adjustment. After two or more months of pissing around I zeroed the rifle in five minutes. B-Square makes the riser (11 mm not 3/8"). It's 1/2 " high and but only fits on a European dovetail, but there are others out there. It's available through Pyramid Airgunmall in the States. As you change your zero you can use the riser to make the gross adjustment and the scope's adjustment for the fine adjustment.
