[QUOTE="Max Heat, post: 851398, member: 43153"] I will be coverting my rem 7RUM to barrel-nut configuration (aka - remage) when my new barrel arrives (about 2 months). Since I will be shooting it quite frequently, and I am now a real stickler, when it comes to maintaining nice and tight HS, I would prefer to use a real gauge. I'm thinking of going with Pacific Tool brand, but they are on backorder for about 3 more weeks. I'm wondering how they stack up against the other brands, but I am assuming they are all pretty much equal. I did have my sav 7RM HS'd a few months ago (before I owned a barrel nut wrench) by a smith for $60 (could have bought the wrench AND a gauge for that), because my primers were really getting flattened, and one even "mushroomed" out of the back of the case. I haven't shot it yet since then, but the fired cases will not even begin to allow bolt closure. I haven't re-sized any of them yet, but I'm assuming they will work when they do get re-sized. Anyways, being that it will not be used very often, I don't think it worth while to invest in a 7RM gauge. But I'd still like to have a means to gauge it occasionally. So I'll be looking for a "cage" (case-based gauge) that has just the right feel, when I finally do get around to re-sizing/loading some cases. And I'm going to hold off on shooting it until that is done. The accuracy of a home-made gauge would be purely dependent on how well it is "calibrated" to the actual gauge, just like a scribed-up bar of steel used for linear measurement will be exactly as accurate as the how accurately the scribe marks were copied over from a machinist's scale.
