Hornady primer feeder - Hornady Lock-N-Load Auto Primer Feed for Classic and 007 Press

Very easy to install and adjust. I was up and running in minutes. I first attached the bolt that comes with the product, but didn't tighten it down. Raised the ram to its full height, placed the feeder tube in the unit, then looked straight down that tube so that I could see the primer cup on the press, the two items will align. Then tighten the bolt with the included wrench. So when you send your brass into the resizing die, a primer will drop in the cup, when you lower the ram, the primer will seat, repeat. If you do need help, call Hornady. They really do have excellent customer service.
