Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

The NECO gauge utilizes v-blocks along with different mandrels and anvils to measure the variation occuring in your cases and loaded rounds. It uses a GEM dial indicator, which can be positioned almost anywhere on the case/loaded round. The NECO tool is able to measure the following: 1) Cartridge case -the curved ""banana"" shape of the cartridge 2) Cartridge case -the relative variations of wall thickness 3) Cartridge case -case head out of square with body 4) Individual bullet -out of round 5) Loaded round -seated bullet runout The NECO gauge is very well made and comes complete with the dial indicator, the necessary chords and anvils for holding different size cases, and most importantly a 21-page instruction booklet. The indicator included with the gauge is a high quality .001"" GEM dial indicator and actually represents a good portion of the cost of the tool. A separate gauge for 50 BMG reloaders is available by special order.
