When the arthritis and torn rotator cuffs in my shoulders started telling me that loading handgun ammo on my RockChucker Supreme was becoming uncomfortable about four years ago, I started shopping for a progressive. I had one for shotshells and knew what the technology would do for me. In the end, I went with a Dillon XL650. I still prefer the RC for my rifle handloading.
Yes, you will spend some serious money for one. With five complete tool heads and most of the options they offer, I have about two grand in mine but the thing works great! It ought to, I agree, but so often in life these days, that doesn't always happen so it's nice when it does.
I don't load for speed so I cannot state how many rounds you can turn out in an hour with any loader but at least several hundred per hour is a real conservative estimate. I insert each case and bullet manually so it takes me longer to load a box than someone with feeders for both but I didn't want an electrical cord to route somewhere or that tall tower in my way when reaching to the shelving behind the loader. Again, since speed isn't a concern, I like doing it the way I do.
I know I'll upset some folks by saying this, but based upon my experience with one set of their dies, I would steer clear of Lee products. Otherwise, there aren't many bad reloading products out there.
