I a single stage for rifle ammo and a turret press for handgun ammo. The turret press save time involved in changing and adjusting dies. The only way to really speed up reloading is to add a powder measure assembly and add powder automatically during the case belling, then seat and crimp the bullet. I haven't done this because I like to verify the weight of every 10th charge and look in every case before I seat a bullet. There are two good progressive presses; the Hornady and the Dillon. Both are very fast once set up, (500 to 800 rounds an hour), but set up and adjustment is time consuming. A friend of mine is a serious competitive shooter, he has two progressives, one for 9mm and one for 45ACP. They're set up an he leaves them that way. Every once in a while he checks the loaded OAL, and refills the powder hopper when it gets down to 1/4 full. He has about $2,500 invested in the two presses but he sometimes fires more rounds in a week than I do in a year.
