Most start out with the tried & true MEC 600 Jr. - generally, no problem at all to load 200 rounds an hour if you pay attention to the loading, and not to everything on your bench, your coffee, your cell phone or any other distractions !!!
Used one (a fore-runner) in 12ga. and another in 20 ga. for years. I bought them brand new for $55 bucks apiece ... ( I did say years ! ) but upgraded in time to the newer models. You can add a few accessories like the bigger shot & powder bottles and auto-primer feed to speed things up a little. A powder baffle also helps to give more consistant powder charges.
In time, I moved up to a MEC 9000G progressive press when I was shooting a lot of .410. Considerable quicker as this machine self-indexes the shell to the next station, and after about 6 pulls of the handle, a finished reload then drops down the eject tray every time you pull the handle ( besides pulling the handle, one needs insert an empty and a wad each pull of the handle ).
The next upgrade was to a Ponsness-Warren ( or P-W ) 950 Elite Grand. Always liked the looks of these presses since I first saw an older version c.1968 or so, so I thought, WHY NOT !. Great piece of equipment. Well made, well-machined and turns out 500 - 12 ga. rounds an hour easily, with no problems at all in the 6 or 7 years I've had it. Biggest challenge seems to be able to keep up to the primer, powder & shot feed requirements !!!
It holds 300 primers, a full bag of shot and easily a pound of powder ... but at the rate you can load, it doesn't take long to run out. Generally, by the time you get down to about 50 primers ( the tray's empty, but not the track ) it's time to replenish everything anyway.
Save money ??? Maybe a little, but you get to shoot a lot more. Only takes a half-hour or so before you go to the Club to load up all the shells you need. If it's a little more than 3 or 4 rounds, sit down for an hour and you can crank out a couple of flats in a hurry.
Highly recommended as part of the shooting experience, unless you make so much an hour you can not afford the time to reload. In that case, send someone out to buy your shells for you 40 or 60 flats at a time !
