What cartridges are you loading? The Big Boss will do anything out there short of the 50 BMG but if you are doing short pistol cartridges you might be better off with the Boss with the shorter throw. I have two Ultramags on the bench but I only load rifle cartridges. It works equally well for the 221 Fireball as it does for the 300 Win Mag. I really like the open front of the C-type press and this is the best one out there. It's absolutely rigid with very tight tolerances. If you go the Big Boss route get the Big Boss II that has the spent primers drop down through the center of the ram. The T-7 turret press woud be an excellent choice as it is used as a single stage press at each station, you just have the benefit of having the dies already set up on the turret.
