Here's a first for me: I installed a new Bushnell Elite 3500 3-9x40 on a set of standard weaver rings. I was using CB shorts (740 fps) and simply feeding each short manually into the chamber.

My first 3 shots were within 2 inches (low) of bulleye at 12 yards. However, I noticed that I quickly ran out of elevation (up) adjustment on the scope. I was very surprised. Any suggestions? I know the shorts are very low power, but at 12 yards, you would think that drop would be negligible. I am sure with SV ammo, this will be less of a problem, but still, very strange.

Do I actually need a 20 MOA rail?

I reinstalled the scope just to make sure nothing was out of alignment.
 
20 moa rail will get you out to 200-300 yards depending on scope, so no, not your problem.

Kind of sounds like a barrel issue, I had that with a Savage, could not get on target (shooting low) at 50 yds with a Bushnell Banner, Savage changed the barrel and all was good.
 
Running CB Shorts in your Tikka may be a problem.
Very low velocity and hardly target grade.
Were you 2" low at 12 yards or did the group measure 2" and was low.
Your line of sight is above your bore.
What are you trying to accomplish shooting CB Shorts? Economy it is not! Have you tried shorts, longs and long rifles?
 
It was shooting 2" low at 12 yards. Tomorrow, I will crack open the CCI SV and see how that goes. I re-installed the scope, taking extra care to ensure everything was in alignment.
I have been shooting the CB shorts for years through various rifles, and never a problem. What I like about them is that they are very quiet and I don't require hearing protection. I want to set-up the rifle so that my wife, who has very sensitive hearing, can shoot it without worry.
 
Get a set of Burris Signature Zee Rings. They come with a set of zero inserts and a set of +-5 inserts. Other inserts, up to, I believe, +-30 are available.

It's easy to mix and match these inserts to suit your purposes, using your existing rail or even the original dovetail grooves on the receiver.

Quick and easily replaced whenever you decide to change you shooting venue.
 
2” low at 12 yards is understandable and won’t really tell you much. Try shooting at 50 yards and see how it goes with a zero. 12 yards is pretty close and will be tough to adjust a scope to that.
My math may be out here but that would be close to 72 individual clicks on your scope dial, assuming either 1/4” or 1/4moa.
2” low at 100 is I. Everything is multiplied the closer you get. That being said, in theory, it’s possible, but maybe not realistically. I’ve never tried that close because 12 yards is ridiculously close and potentially dangerous depending on the target.
 
Shim the rear base up but don't torque the top scope rings down hard. Your scope will point slightly down, giving you more elevation for your chosen distance.
 
It may not be possible to "zero" for 12 yards without some extreme offset to the scope. The bullet is likely still rising to the line of sight and 12 yards is simply not enough distance for this to happen.
 
Your scope is 1.5" above the bore so to get it to shoot to point of aim @ 12 yds you'd need the same amount of up as if you were shooting @ 300 yds or more so no, most scopes won't do that. Try 25yds and all should be better, 50yds better yet.
 
Hi all. First off, thanks for all the replies--most helpful!

Yes, I have never zeroed to such a short distance, and what a learning experience it has been.

I tried the CCI Longs (segmented hollow points, 710 fps) at 40gr. They are a bit louder than the 29gr 710 fps shorts, but just barely allow me to shoot to point of aim at 12 yards. When I stretch her out to 20 yards, all is well.

As suggested by a few, I might invest in the Burris Zee rings and use a 5 MOA insert.

This is exactly what is happening. Thanks for the clarification.
 
How's the sight picture at 12 yards with that scope? You might want to get something with adjustable parallax for shooting that close, the Elite 3-9 are set for 100m.
 
I just ran the numbers in my ballistic calculator for my 22lr precision rifle rig. Looks like I run out of elevation (21mil up available on the turret from a 50m zero, 30moa rail, Athlon Cronus BTR 4.5-27x56, CCI Standard Velocity 22lr ammo) at about 340m at the far end and 2.5m on the close end

Seems to be shooting point-of-aim. I just need to slightly compensate with the scope due to maxed-out elevation. I swear by the Elites for general duty applications. This includes, but not limited to, tree-rat dispatching. :)

Have you tried reduced velocity "subsonic" ammunition???

I have a ton of the Elites as well, great scopes, good eye relief and handle the heaviest recoil...I just never tried one on a 22 or at close range, good to know they work for that as well.
