So, filling primer tubes sucks. And as far as I can tell all the automated tools to do it also suck. I know people love the frankford and hornady gun type things but my testing with them didn’t prove that successful. What I want is a static mounted machine that will fill tubes that I put under it. I get that the vibration flips them all over using a standard primer tray ribbed surface and that’s great, that part is a no brainer. The trick seems to be to get them to move over a hole which allows them to drop down, WITHOUT tilting and jamming as they fall off a cliff. So, does anyone know of a design theory that will help here? I’m a machinist and have some decent tools and skills at my disposal. Let’s get nerdy!
