[QUOTE="cross, post: 1479988, member: 8592"] Whooooo!! Cool! A shooting nerd! My favorite. Ok, here’s something I thought about trying to design but ran out of gas. Maybe you will find it interesting and can figure it out. So, a widget that uses either pressure or weight to measure the volume of individual brass cases. I’m sort of envisioning a little rubber plug that fits up into the primer pocket to make a seal then the other end might seal against a big rubber gasket. Some gas is pressed into the case and either the amount of gas or resulting pressure gives you a measurement that can be used to find the volume. Filling with liquid is a mess so I don’t want a water measurement. I also wondered about seeing if the thing that puffs air into your eye at the eye doctor might be applicable. Anyway, that’s my idea. Thanks, Cross [/QUOTE]
