10/22 Sight-in Problem

Help!

I just added a Butler Creek carbon fiber barrel and target stock to my 10/22 this weekend. Everything wen't fairly well until it came time for sight-in. I'm hitting about 6" low at 50 yards and am out of travel on my elevation adjustment. I have fairly low rings and a Leupold 3x9x32 on the rifle right now.

Any suggestion on what my options are at this point? Would different mounts likely help? Or possibly another scope of some sort (more adjustment?).

Although the optics quality on the Leupold is great it doesn't seem to have a wide range of adjustment. I have one on my Ruger 77 and it's finr. I tried mounting the one that's currently on the 10/22 on a Remington 788 and ran out of travel on it also (on that rifle I was about 1" high at 100 yards with no more adjustment possible).

I'm debating what to try next. Any suggestions would be appreciated.
 
New scope

I would just go out and buy a cheap scope, try sighting in with that, if it does sight in, the luepold is junk. I would never think i would say that about a luepold:eek:
 
Sounds like there's something wrong with that Leupold. Have you tried mounting the 77's scope on the 10/22 to try to rule out the rifle and rings/mount?
 
I don't think it's the Leupold itself (although it may be it's lack of adjustment range). I had it on my other 10/22 (a stock Ruger with factory barrel) and it zeroed fine on that rifle and zeroed fine on another Ruger 77 that I had it on initially. I just swapped it from my other 10/22 Saturday and I've used that rifle recently so I don't think anything could have happened to it since then.

I probably will try another scope though (I do have a crappy Bushnell 4x laying around) and se what that does.

Is it possible I installed the barrel wrong somehow and it's not quit right? Seemed like a pretty simple barrel swap without much chance of doing it wrong but I guess I could be missing something. Everything functioned fine though and it shoots consistantly, if low.
 
One thing to try

Place a shim under the back of the mounting rail, like a very thin aluminum washer.

Was the same scope okay on the rifle before the barrel swap? Does it have this problem on a different rifle?
 
Yeah, my dad reccomended shimming the mount also. Is that a common thing to have to do?

It was fine on the 10/22 I pulled it off of, and fine on my brothers Ruger 77 before that. When I had it on my Remington 788 I had a similar issue although in that case I was shooting about 1" high at 100 yards when I ran out of travel adjustment.
 
You might suspect the butler creek barrel setup if the rifle was shooting okay until the barrel swap. Make sure the barrel is seated completely into the receiver and the v-block is installed properly in the groove, properly torqued, although its awfully hard to foul up the installation itself. As a control, try installing the stock barrel and see if you still have the problem. This is one time where changing the barrel is easier than changing the scope!
 
I agree with David, change the barrel back first. You may have to shim the front of the barrel. I have a 10/22 Target and it's bull barrel isn't floated. Just a thought.
 
If the barrel change doesn't work (or at lease brings the POI closer to the bullseye), then you must do what Ledbetter says. Get your shim from your favorite beverage container.
 
support at front of barrel

Is your barrel fre-floated? If not, it should be. Either way, you can put a "pressure point" under the front of the barrel where it sits in the stock, as Danny45 said. Many shooters do this to tighten up their groups.

However, six inches at fifty yards is a LOT of rise to achieve with a barrel support. If the gun shoots well, shim the scope mount instead. If the gun is not shooting well, reexamine your barrel mount geometry and screw torque again.

Regards.
