Last Loaded ammo I found was $5.00 a round! However, Starline makes brass for it and you can use standard 9mm projectiles. For dies you can use 9x19 or 9x23 dies although I got a set of true 9mm WinMag dies from RCBS. Loading data is available but hard to find. If I find any other owners, I'll be glad to give `em all the data I have. I am pushing a 147gr JHP @ 1,400fps or so right now.
It's a great conversation starter at the gun shows. I often work the VCDL booth and leave it and a single bullet out to draw folks over for a peep.
