Sounds to me like you have set the space tighter than it was originally. This is not necessarily a bad thing, I tend to sent my chambers about as tight as I can get them and still function properly. It helps with my case life and case stretch.
New brass tend to be a bit smaller than a Go-gage and cheap scotch tape tends to be .002" thick, so this will result in a slightly tighter headspace over the gages that are normally designed for a .004"-.005" difference between Go and No-Go.
Now figuring the distance you are smaller. Barrel threads are 20 Threads Per Inch (TPI). So 1 full revolution will move the barrel .050". From your description it sounds like your barrel is rotated roughly 1/4 turn from its original position, so that would be .012" tighter. If Savage set the headspace closer to the No-Go then your barrel may have been factory set +.005" and then if your brass is say -.005" on the small side (some may be even more under) then from factory spacing you could be .010" tighter, give or take under the very loosest your headspace was originally set.
So basically you just went from being on the loose end of the tolerence to the very tightest end of the tolerence.
No matter what, its your rifle and your face behind it when you shoot it, so if you have any doubts, wait for the gages.
