[QUOTE="Kevin Thomas, post: 369196, member: 15748"] Tom, I like them, and there's several on the market. My point is, you can't know if you're improving something if you don't have a baseline from which to start. As I mentioned, if you use the gage, you may very well find out that the standard dies are doing a good job for you. There's also (as I mentioned) several ways to get better concentricity from standard dies, such as raising the ram about a third of it's stroke after he bullet begins to be seated, then turning the cartridge in the shellholder about 120 degrees, raising it another third of the way, and then repeating this for the last third after turning the cartridge another 120 degrees. A simple thing to do which frequently does improve concentricity of the finished round, but again, if you can't measure the results before and after, how do you know? That's where the gage comes in. Yeah, they're worth the time and money. Take a look at the gages themselves, but yes, many will measure various aspects of brass, bullets, the finished cartridges, etc.. I have several sitting around here. As you might imagine, things like this tend to collect around me over the years, but yes, I do still use many of them on a regular basis. My personal favorites would probably be either the Sinclair, or the NECO gages, but there are a number of others out there. They all do basically the same thing, but they each have some specialized applications that may or may not apply to what you're doing. It's a personal decision there, and you'll need to decide that one for yourself. Hope that helps! Kevin Thomas Lapua USA [/QUOTE]
