Default Weaver scope issues

I just received my Weaver K2.5 back from Iron Sight, Inc. Repairs took 12 months and work appears to be fine. One problem, however. I shot a Vintage Sniper Match yesterday and I fired very high. I ran the scope elevation all of the way down and bottomed out. Still shot high at 200 yds. Not sure what is going on. Any ideas out there? Thanks, guys.

When you got that scope back reticule was centered. When it was mounted it would have been best to leave it as close to vertical center and shim base rather than take it out on scope.

When you got scope back what did they say need fixing on scope?

Iron Sight fixed the fixed power erector cell and also checked windage and elevation. Cleaned and resealed with new nitrogen. I am going to buy new low rings and re-mount the scope. The work on the scope appears to be first class and Iron Sight has a solid one year warranty. I will try to fix the problem here before returning the scope.

Shim the base. Aluminum can makes good shim material. Good Shooting. .

This is on an 03-A4 with Redfield base and rings. Shim front and rear base or just front base or just rear base? Thanks.

Front only. If you have a way to hold the rifle firmly you can center the reticle first and then shim the front until it approximates the location of your bullet hole (without moving the rifle) and you will be close.

I'd say that you probably need to shim the base. I don't think vintage Weavers were ever filled with anything more than hot El Paso air. All they have to keep them sealed is a rubber o-ring that sits between the jam nut and the rear eye piece, and it isn't the tightest assembly going either.

By all means, always get the rear base flush. That rear dovetail varies in height by a bit from Rec to Rec. Usually this is done when fitting base at mock up, as you don't want the base bending or have to stress when screwing it down.
