Is it big enough to fit the Federal primer box, like he was asking, I don’t think so. And if it is where did you get it, who made it? You really should try to be helpful instead of quoting out of context.
I have a green RCBS plastic primer tray that seems to work just fine with even the Federal packaged primers.
It's not hard to slide the box out and have all of the primers easily end up in a normal sized primer tray.
