with the scope rings on my SRH 480. When mounting my Leupold 2X, I noticed that the front ring base had a large burr on it. (this left a nice scratch down the bottom of the scope after a few shots as it slipped) While removing the burr, I noticed the following: if I placed the scope in the bases without the top of the rings on, when I applied pressure on the scope directly above the front base, the rear of the scope would lift ~2mm off the rear base. Obviously, the rings were not lining up. I contacted Ruger, and they replaced the rings. With the new set, I had the same problem. If I tighten the screws, I risk ruining a $200 scope. After speaking with Ruger again, they want me to return the entire gun. Needless to say, I'm beginning to get a little upset over the situation. I prepared to lap the scopes, making a tool from a piece of 1" stainless ground barstock, and some valve lapping compound. But there is alot of meat that must be removed to make these rings line up. Do I risk removing too much, where the rings won't be able to hold the scope tightly?
Also, Ruger sent me a bag of powdered rosin to put between the scope and rings. Perhaps this will aid in keeping the scope from slipping.
Does anyone have any good suggestions on the proper way to lap rings?
I'm anxious to shoot this gun again!
