BobbyG, FWIW, I reloaded on a single-stage for over 20 years, rifle ammo only though. I got into pistols two years ago, realized the very first time I tried reloading some pistol ammo on the Rockchucker that progressive was the way to go.
I considered the Lee Turret briefly because it was cheaper, but the idea of having to spin something four times and pull a lever four times just to make one loaded round didn't sit well with me. One spin, one pull, one round is much, much more efficient.
I ponied up the dough and got a 550b with the stand and a few conversion kits. It paid for itself within the first 6 months! I drank the kool-aid and I recommend you do too, blue or red seem to be the tastiest!
I have several presses now. A beefy single stage for doing all the "dirty" work like pulling bullets and full length resizing. A Lee turret for pistol and most of my rifle, and I am just in the middle of getting a Redding T-7 with competition dies for my .223 and .308. In the past I also had a Dillon XL 650. While the single stage is incredibly simple to use and solid, for reloading handgun ammo it is just not the way to go. I keep the Lee turret for that.
My first buy I thought was going to be my last, an XL650 with all the bells and whistles. The learning curve is steep, and a screw-up at one stage is a screw-up that can, and a lot of times does, carry through to following stages making for a 'fun' time sorting out the disaster. The worst is when a primer gets missed and soon after there is H-110 gunpowder everywhere. It can take an hour to disassemble everything, clean it up and get it back to the stage that you are making ammo consistently again. They are wonderful presses and while most screw-ups are user error and with experience can be easily avoided, there are still some which creep in to make a reloading session less than amusing.
So saying, I bought a Lee turret to make .308 rifle ammo although I never used the auto-indexing feature. I'd just hand rotate the turret to the die I required and made up 50 or 100 at each stage. It is easy to maintain consistency when repeating the same process and with care there is little to no chance for user error.
Within a short time I decided to give the Lee turret a go for 45ACP as well, bought dies and a turret, stuck in the indexing rod and fiddle farted around until it worked perfectly. A year later the XL650 had been sold and I had a couple more turrets and die sets to reload my other handgun ammo, mainly .357 and .44 mag which I had been doing on the Dillon. While I could run about 300-500 rounds per hour on average through the XL650, I found I could do about 150 rounds of auto-indexed pistol ammo through the Lee turret which suited my handgun reloading needs perfectly.
Over the past several years I have been getting involved in more precision long range rifle shooting and I am taking it to the next level with the Redding gear on the ammo front.
Now, I know this isn't helping you out with your difficulties with the Lee press but it really is pretty straightforward to adjust and get working perfectly. There are only two really frustrating parts on it. One is the little square nylon bushing. If it needs replacing, and it will every 2000 to 3000 rounds, it MUST go in the correct way. Damned if I can remember which way that is without it in front of me. At the same time you have the clamping assembly off to change out the indexing ratchet, make sure everything inside is 100% clean. Blow it out with about 50-60 lbs of air. No oil, powder, dust, dirt, etc. Carefully and firmly clean the indexing bar with some WD40 and a clean rag to remove any gunk which may have slowly built up over time. Put it back together with the bolt done up just firmly enough to hold the assembly in position. Too tight and it warps, too loose and it twists and turns a bit in use which makes for indexing grief, either not aligning properly or jamming on the indexing bar. The other part that I still have a bit of trouble with is the auto-prime feeder. Usually the last one or two primers will not feed. I have given up trying to adjust it. I just pop them out into my hand and manually put them into the priming cup.
Two items which will damage a Lee turret press:
1) short stroking. Make sure the arm goes all the way to the top and all the way to the bottom on each stroke. This ensures that little square black indexing ratchet will rotate freely when it has to.
2) manually trying to index the turret with the arm not fully raised (ram lowered). Basically another version of the above, almost guaranteed to damage the indexing ratchet.
