For that quantity, 3K, and the cost of'm, free, I'd hafta aggree the swager would be the best bet. But it also depends on what a guy's shootin.
I got 400 cases and shoot a NEF single shot, those 400 will last me a LONG time. I can process 100 and be happy. And ya know, with a few of those pockets, the primer slides in a little on the easy side, but I haven't found it to be a detriment.
But, if a guy is shootin a black gun,,,,,the swager will pay for it's self pretty quick.
