[QUOTE="codyadams, post: 1595564, member: 87243"] I have shimmed this way as well on an old 98 mauser that had been sporterized by a garage gun smith and no generic bases would work. I have had what you explained before, it is usually caused by one of a few things.... Poorly manufactured bases/rings Poorly installed barrel Poorly drilled base screw holes Front/rear of action wjere bases mount are not within spec I had a rem 700 that the front and rear screw holes were offset, and during boresighting ran out of windage adjustment trying to zero. This also means that there is some bad stress going on with any standard type rings, and being applied to your scope tube. I used burris signature zee rings and was able to shim to zero, and it also took out the stress by self centering. Personally, enough of an offset in rings to not be able to zero a scope with 85 MOA of adjustment would be a major cause for concern, that is around 40+ inches off from center at only 100 yards. either there is an offset from your front and rear rings (caused by either an out of spec action or out of spec rings), which would cause a large amount of stress on the scope tube, or the barrel was not installed square to the bore axis. Judging from the look of that fine rifle, I would lean more towards rings or action base mount area not being in spec rather than the barrel installation. Would not be out of the question for a remington action. Just my thoughts [/QUOTE]
