Re: signature ring problem
Goodgrouper has asked good questions already and that may be the issue at hand. Have you used this rifle with a different mounting system with no problems?
I have seen several Savage receivers that had the rear mount location dramatically lower then it should be. In fact I see this enough not that I check every one that comes in. The easiest way is to put on a one piece base and just snug down the front two base screws and look at the clearance if any between the rear of the base and the receiver.
If there is any significant daylight between them, you should really shim the rear of the base. I have seen many Savage receivers that needed a 10 thou shim and a couple that needed 20 thou and one that even needed a 30 thou shim.
You can order shims from Brownells that are in uniform thicknesses and make this job much easier and higher quality then most other types of home made shims.
I had a personal Savage M111 receiver that I made into my lightweight 270 AM rifle. The rifle was amazingly accurate, still is, but I needed 30 thou of shim to support the rear of the base between the receiver. You can imagine the issues that you would have if you just torqued down the rear of the mount and dropped the rear of the scope 30 thou below the front!!
This is not uncommon and easily fixed, just get a thicker rear shim. To be honest, I would put the "0" inserts back in and play with the shims under the rear of the base until you get the scope level and then you can use the inserts for more moas if you want.
