shimming a scope ??
 

Just a quick question on a scope. I've never had this problem with a scope before. I got a good deal on a Bushnell 4200 E-lite and decided to put it on my encore, so I took the Nikon 1.5-4.5 and put it on my Renegade. [Don't tell anybody]. Anyway I used some Weaver Grand-slam QR medium rings, but can't get enough height adjustment, still 5" low at 50 yds. Just wondering what is the best way to shim the rear of the scope base to get enough height? Do you think the problem would be in the scope or rings. Same base as with the nikon and hadno problem?????

I have seen some of the finest gunsmith's out there shim mounts before. But the bottom line is if you need to shim ascope then there is something wrong. A shim is simply a band-aid. It is not the proper way to do things. You need to figure out what the real problem is. All a shim wil do is put a temporary fix on a permanent problem.

Personally I have heard from several shooter's that the biggest problem with the Elite's is the lack of enough internal adjustment. How many minutes of adjustment does your scope have?? And if you are 5" low at 50 yards. At what position are your internal knobs at to be 5" low?? Tom.

First thing I have read they do is reverse the bases, from front to back. This will sometimes raise the scope. As for shimming, I have a gun smith do that.

I did purchase a while back in the 70's from brownells brass shims for shimming a scope .
I think if you need to shim the bases i would use a aluminum soda can I think they are about 4 thousands
I have another idea try going up one size in the ring height

I agree, You should not have to shim a scope to get enough adjustment, it has to be the rings, it is a one piece weaver base that worked fine with the nikon scope. I am going to swap rings with another rifle and see what happens. THANX FOR THE REPLYS !!!!

I install a lot of scopes on guns.All Simmons rings, some Leupold rings andmost Weaver rings are being made in China: Not sure about your QR rings-have not installed a set lately.Had so much trouble with these made in China rings thati willnot attempt to install them on a gun.

I'm not sure if the problem is with the encore, but it sounds that way. The mounts are installed directly on the barrel, right? If it won't shoot high enough, the problem is with the mounts. You say you will try new mounts, and that's probably best, but as Cayugad said, sometimes swapping the mounts front to back will help. I don't know about that particular scope, but some can be damaged if shot when adjusted to the end of theadjustment range.

So what exactly is the permanent problem? One can put on a different set of scope mounts and the problem very likely might disappear altogether. I wouldn't call this a permanent problem just a compatibility problem between the gun, the scope mounts, and the scope. There might be some rifles that would need shimming with any mount or scope you might put on them, but I think such rifles are not very common. The use of a thin shim on such rifles will absolutely not alter the guns reliabilty one bit either.

The permanent problem is probably the mount.
