I ordered and received a Swarovski 1-6 x 24 scope for a Kimber Talkeetna that my wife gave me for Christmas. Along with the scope I received the Talley rings and bases (part #25X840) that I ordered. So last night I mounted the bases and torqued the screws to 25 inch lbs (using my Wheeler FAT wrench) per Talley's recommended torques. Note: the screw holes of the bases line up perfectly with the screw holes on my Talkeetna.) I loosely put the rings on the Swarovski, but the rings just didn't seem to lay right on the bases when I put the scope on the rifle. Anyway I snugged up the ring screws so that I could shoulder the rifle and look through the scope when I noticed that the muzzle end of the scope seemed to be higher than the rear of the scope in relation to the rifle barrel. My wife also thought the scope was aiming uphill. Perplexed, I removed the scope and rings to make sure that both rings were the same height and they are. So I laid a metal ruler across the Talley bases and found the rear base is about a 3/32" lower than the front base (about the width of a nickel). The height difference accounts for why the scope rings didn't seem very stable on the bases before I snugged the ring screws down.
I rechecked the Talley part number of the bases for a Kimber 8400 and they should be the correct ones. I guess I'll call Talley this next week to see if they have an explanation for the height difference, but has anyone ran into this issue with Talley bases on a Kimber 8400? The difference in height cants the front of the scope up so much that I'm positive that I won't have enough adjustment in the scope to sight it. Any and all thoughts and associated experiences are appreciated.
