Well, I got things going today with my new 550B and after a bit of stumbling I got 200 357 mag. rounds loaded up. Next up is the 45 Colt and then a few trips to the range. I think the capacity of this thing is going to outstrip my shooting time by a considerable margin. However, I'll definitely be doing more shooting because of it, that single stage press makes good ammo but the time investment was just too much.
