Church ain't got nuthin to do with it . . .
I think it's wise for anyone to learn what is going on with a single stage first. I'm not saying you can't jump right into a progressive. I just think you would get a better understanding by using, or at the very least watching someone else use, a single stage. There is something to be said for handling the cases several times in the beginning. You gain several things from this.
1. Appreciation and understanding of what happens at each stage.
2. A feeling for what each stage should "feel" like as you are running the press handle up and down.
3. A crystal clear mental picture of what the cartridge should look *and feel* like before and after each stage.
4. An understanding of what you will be gaining *and loosing* by loading on a progressive.
You will save a *lot* of time and loose a small amount of safety (some say accuracy) by switching to a progressive.
I'd recommend getting a single stage or turret to start with. It's not like you will never use the single/turret again once you get a progressive. There will always be reasons to pull out the ol' single stage. Mine has never moved since it was originally mounted to my bench. I still use it on a regular basis for low volume work or for little things like depriming before a wet case washing.
I use RCBS presses, Rock Chucker & Pro2000. These things will survive a nuclear blast. The priming system on the Pro200 makes every other one I've seen and used look like a dangerous joke. It's the main reason I bought the Pro2000 and I am very glad I did. Primer strips are available from CCI or you can buy empty ones and load whatever primer you feel like using in them. I do anywhere from 300 to 450 rounds an hour and I am NEVER in a hurry when I reload. Death will come fast enough without rushing the reloading process. Besides the ER is over an hour away and it pisses off my wife when she has to stop what she is doing and take me to the ER.
Lee and RCBS dies. I like the Lee dies better regardless of cost. They are so much easier to adjust it's not even funny. And despite looking "cheap", they make better, more consistent ammo, than the RCBS dies.
Lyman digital scale / powder dispenser. It works ok, I'd get something else if I did it over.
Lyman tumbler, works just fine. I also use fine walnut from the local feed store for $11.00 a 50lb bag. Throw in a used dryer sheet or two with each batch. Keeps the dust down and pick up fine particles.
L.E. Wilson Max Case Gages. Nice to have one for each caliber. You can use the barrel off your gun to start out, works the same. The gauge just saves you the time of tearing the gun down and putting it back together.
Hope this helps . . ..
