Honest opinions here
Warhawk -
I started on an RCBS single stage in 1980 and then sold it and bought 3 Lee Pro-1000 progressives later on. I could never get any of the Pro-1000s to go through a full reloading session without something happening. Even after swapping parts around between the 3 machines something always needed attention. And this is saying a lot because I design, engineer and install precision machines for a living.
So if you want my HONEST opinion, then....
• Start with a USED steel/iron single stage (RCBS, Lyman, CH, Redding, Hornady, etc). Look on CraigsList and try to buy someone's complete setup so that you get books, calipers, scales, dies, case trimmer, powder hopper.... all the accessories. Then learn the reloading process and safety steps going slow.
• Then by the time you're ready for a progressive, you'll know what makes sense to YOU for YOUR type reloading. You'll already have your books, dies, calipers... all you'll need is the progressive press.
• You'll still need/want a single stage for de-capping, test rounds, specials, low volume rifle ammo, etc. You never outgrow your need for a good single stage press.
• The Pro-1000 was Lee's first attempt at a progressive, and frankly it was not a good effort. The press itself is NICE... but all the accessories are seriously lacking, especially the primer feeding. Honestly, you'll find yourself constantly fiddling with the press and various accessories until you are sick. If you are not mechanically inclined you'll be lost very quickly. Lee makes much better progressives now than the Pro-1000.
• If you simply MUST buy a progressive press, make sure to buy a minimum 4-position press. Sometimes you simply need 4 positions, maybe only because your die set is a 4-die set. If you have 4 or 5 positions and only need 3, then there's no harm. BUT if you have a 3-position press and you need more, you'll be in deep guano.
• Realize that the accessories from one brand progressive will NOT adapt to another brand. So by the time you setup ANY progressive for 3-5 calibers you'll have too much money invested in shell holders, die adapters, etc to turn around and buy the press you really wanted/needed. So choose a progressive press VERY carefully my friend. Which gets us right back to point #1, buy a used single stage first.
Reloading in itself is a huge learning curve. Progressive presses by themselves require another huge learning curve. Without a lot of mechanical aptitude and knowledge of ammunition, IMHO jumping right into a progressive reloading would be like learning parachuting and jungle survival skills by being pushed out the door of an airplane!!
