[QUOTE="QuietTexan, post: 2141867, member: 116181"] Two different things. The bullet comparator is used to measure base-to-ogive (BTO) measurements, either of the loaded cartridge or of an in individual bullet. It's used in conjunction with a seating depth testing method (Hornady modified case, split case, stripped bolt, etc) to set seating depth when loading rounds. LE Wilson makes two types of drop-in case gages. Their "case gage" measures min/max headspace and case length. It's reamed out larger in the body than SAAMI minimum spec so that you can put fired brass into it, and combined with their depth micrometer measures headspace. This is similar to what the Hornady Headspace Comparator kit measures: [URL unfurl="true"]https://www.hornady.com/headspace-bushings#!/[/URL] The second one they make is the brass "min dimension gage" which acts more like the other case gages on the market in that if the round drops into the gage it will chamber in any rifle chamber because it's less than max SAAMI in every dimension.
