After seeing how much is spent on a receiver and separate base, then another base for that receiver and bedding 4 rings .... ugh. Why not just get a receiver with integral base like the Lone Peak Fuzion and ARC rings or a Spuhr mount and be done with it? Also, funny how Murphy’s law works and the only time your scope shifted in the rings was the two shots you took on game not during load development or range time. Sure is cool it stayed put perfectly for a measurable follow up both times ...rather be lucky than good any day.If you talk to Ryan Pierce of Piercision Rifles, he beds every scope in the rings, and he says the same thing, that the fit is tight enough that he can lift or nearly lift the rifle after lightly pressing the optic into the ring bases. It has nothing to do with needing lapping, there is no binding, lapping would be counter intuitive, a good bedding job gives 100% contact of the rings to the scope, not 95% or 98% like a really good lap job might do. And as far as what I did first, was exactly what you just said....I am switching from DNZ one piece base to a rail base and set of 4 rings. The base will be pinned with either 2 or 4 pins.
