This question gets asked about every two weeks, and every time we jump all over ourselves trying to be persuasive. Here's my attempt:
When I started loading, I tried to go cheap with a Lee 35th Anniversary setup. Everything I got in that kit is now gone. I was able to reload accurate and safe ammo with it, but it felt flimsy and didn't inspire confidence, IMHO.
Then I bought an RCBS Rockchucker IV press. Very sturdy and smooth, but I never liked the way it handled spent primers. After years of reloading on the single-stage RCBS, carefully using loading blocks to check powder throws from my Redding powder measure, I became intrigued with the idea of a Lee Classic Cast Turret (LCCT) press and bought one.
For me, there are a couple advantages to the LCCT over the single-stage press. First the reloading dies stay set up in their individual turrets, and I use the Lee 3-die round storage boxes to store the turrets. When I'm changing to a different cartridge, I can easily exchange the turrets and shellholders in less than a minute. Not a ton of time saved, but noticeable.
Another benefit is that using the auto advance feature lets me eliminate three "insert case/remove case" steps for each round. Another significant time saver.
The final item that I really like about the LCCT is that I can easily check each and every case for a proper powder throw before seating a bullet. I use a an LED flashlight mounted next to the LCCT to accomplish this:
But rcmodel is right, you MUST have a process for checking powder drops in EACH case, no exceptions. And case blocks are the best way to do this with a single-stage press.
Since I like to prime my cases with an RCBS hand priming tool, I've had to adjust my process to prime my cases first, then they go on their merry way through the LCCT: 1) resize case (with no primer decapping pin installed), 2) flare case and drop powder, 3) seat bullet, 4) crimp case.
With this process I can easily reload 200 rounds an hour, and have been able to resist the urge to go totally progressive. The only rifle round I reload for on the LCCT is the .223 (with a double-disk kit), but I think you could reload for .308 as well.
The .30-06 requires more powder than I can throw with the double-disk kit, so it gets done on my Lee Classic Cast single-stage. Yes, a single-stage press always comes in handy, and I've replaced the Rockchucker with the Lee.
So there's my way of reloading. Will it work for you? I have no idea. There's nothing wrong with starting with a single-stage press and learning from your mistakes (which we all make). But if you think you might like to go a little quicker some day, then you could always purchase the LCCT, take out the auto-advance rod (less than a minute to remove or install), and use it as a single-stage. Then when you feel like you're ready for a little more production speed, install the rod and you're there.
