[ARCHIVED THREAD] - Scope on pellet rifle shooting a foot low?

Posted: 1/17/2006 6:36:47 PM EDT

I just bought an RWS 34 pellet rifle and Bushnell 3-9x32 scope and started to sight it in today. Well the pellets land about a foot directly below the center of the target. I thought the rings were backwards (if you could even do such a thing) so I reversed them and the same thing happened. You guys have any tips?

Yeah, adjust the scope's elevation. That's that knob thingy on top of the scope.

First, buy an airgun scope, that gun will destroy a regular scope. If you still have that problem, throw a shim in the back ring.

+1 a magnum powered pellet gun will eat up a regular scope like you would not believe. I killed one after putting it on a Beeman pellet rifle.

It is an airgun rated scope, and I am out of elevation on the scope.

Then your only option is to shim the (rear) base. Actually at the ranges an airgun is effective a scope is only marginally useful anyway.

Back up to the 50 yard line! it's not a 300 yard rifle!

Seriously, shimming is probably your answer. Any gunsmith oughta have shim stock. Just tell him how much error you have and he should be able to dope out how much shim you will need.

Good advice on the airgun/scope issue even though you were luckily knowledgable enough to know better. Something to do with how airguns recoil forward rather than back like a normal firearm.

Please expain this shim the rear base thing. Best material to use? Under the actual mount or under the scope?

You can buy shim kits from Brownell's--or you can make them from aluminum ~~soda~~ beer cans. Be creative with a tin snip. I once used a pop can, tin snip, and paper punch (to make the holes for screws to pass through) to make a shim for a cheap rifle. You just put the shim(s) under the rear base, which raises it and positions the rear of the scope higher, which is the same as raising the rear sight, and thus the point of impact.

Shim can be bought a most gun stores. On an air rifle a piece of beer can and E-tape can fix it right up. I know I'm cheap, but the beer can plus e-tape (for grip and a non-scratch surface) is about the perfect thickness.

Damn: Beekeeper beat me to it.

Yeah i have a buddy who gets some kinda sick thrill out of sporterizing military bolt guns. He does this all the time. It's no big deal. Make sure you torque the screws down well.

Just stay the hell away from my military guns or you're gonna pull back a stump! he he he

Ummmmm .... how far did you set the target? It seems that the pellet may not be "reaching" the target.

I promise this air rifle has enough juice.

Eidt - one peice of soda can and e tape did not really chanige the POI.

Wait shouldnt I shim the front scope ring?

No--think about the line of sight vs. the line of the bore.

Only if you want to be 2 foot low.

Raising the rear causes you to bring up the front to get it in line, raising point of impact.

so... what is the distance your trying to reach?

You might try the RWS C scope mount that is made for the air rifle if you aren't using it now.

I am less than 60 feet for sure and probibly closer to 50 feet. I shimmed the rear with a peice of a soda can bent over its self and enclosed in e tape. That rests below my scope on the rear mount, see below.

>-||----------||------< <Scope and rings
__#
__||_______|| < Mounts = ||
=================---------------------- <Reciever and barrel

Shim = #
Ignore the ___ in front of the shim and the mounts (they are there for spacing only)

I cannot mount the shim under the mounts because the mounts have curved bases and the shim doesnt raise the mount.

I had the same problem on my airgun. After 2 different airgun scopes I found the RWS-C mount.
Solved all my problems.
BTW...I was considering getting the same gun...Other than shooting a foot low haow do you like it?
I am looking for a gun to shoot pigeons and rabbits.

I bet it will be a nice rifle once I get it sighted in.
