So... swung by Wilson on the way home, after sitting thru 1st Aid / CPR training, after a 12 hr night shift. Ugh.
Seems like a nice little press; sounds like they've been working on it for a little while (year or so), waiting on machine time to be able to bring it to market since pretty much everything other than the screws holding the top plate down to the rods, and the linear bearing, are made in-house.
Primers go straight down the ram; there's a rubber plug at the bottom though I imagine a person could stick some plastic tubing up there to route primers to a container if they wanted. Uses standard shell holders, captured by a claw that tightens down with a provided wrench so they stay a) in place and b) indexed the direction you want, for left or right handed operation. The handle swaps from one side to the other as well.
As far as the size... I didn't take exact measurements, but it looks like has plenty of room for the majority of cartridges that most people would want to use it for, i.e. the usual .223 Rem, .308 Win, .30-06, .300WM, RUM, etc. sized cartridges. I'm guessing it'd probably handle something a little bigger, but how much I don't really know.
They hinted at some possible accessories/attachments such as a way to use it with their seater dies.
