[QUOTE="daveosok, post: 59549"] I can say this with absolute certainty. If your action I.E. Remington is the action being used I don’t care how accurate your rings are the action isn’t. Yeah Marty rings are superb I have a set and yes I lapped them. The Remington action diameter is approximately 1.350 in diameter; the drop in distance for the rear scope base mounts is according to blueprints is .118. You’re using approximate measurements with precise rings and you’re expecting them to line up perfectly? I used a coordinate measuring machine, a device that uses a probe to measure dimensions and it is very accurate and one of the only ways to measure some dimensions. The drop from the front scope base area to the rear scope base area on this particular action was .11975. Now if Marty’s rings and bases are made to account for this exact figure then they will most likely line up but I doubt it as the actions are belt sanded while spun on a rod by hand. Do you think the outside diameter of such an action is straight doing it by hand? I don’t think so and not even the most experienced smith or machinist would tell you that hand forming is one of the most accurate ways of bringing in a dimension. So lets say Marty’s rings are based off .118 which I’ve seen a section of the blueprints for the rem 700 and it happens to be .118, you have a difference of .00175 that still means they don’t line up despite Marty’s excellent product. So why lapp rings that don’t need to be lapped is clearly explained here with the inaccuracies of manufacturing deficiencies. More often than not the actions are a lot more out than one would expect and I refer you to my other post where I mentioned the .011 thou clean up it took to get the action parrelle this would have meant that the .118 dimension was indeed something completely different with the .0055 taper per side and once again reaffirming that exact rings dont make exact scope mounts as the actions arent exact either.
