In another tread (Lee Turret Press and Tall Cases ) I was trying to solve a problem of being able to see small powder charges in tall cases (357 and 327) using the Lee Turret Press ( basic not classic). I eventually found a work around, but for the long term I need to consider other alternatives. I shoot 150 – 200 rounds per week and growing.

My loading procedure is:

Case Preparation

Tumble cases when I come back from the range using a Lyman 1200 Tumbler
De-Prime and size using a Lee carbide sizing dies on a Lyman Spartan Press
Inspect cases and clean primer pockets
Prime using a Lee Hand Primer (never could feel the primers seating with a press)

These steps are pretty quick and can be done when time is available.

Load with the Turret Press using auto indexing

Set up:

Lee Auto Drum Powder Measure in Position 1
RCBS Powder Checker Die in Position 2
Bullet Seating Die in Position 3 (I manually look into case before seating bullet)
Factory Crimp Die in Position 4.

I like this approach but want to speed things up a bit.

One way is to move to the Lee Classic Turret Press which is taller and should speed up the inspection process of manually looking in the case (as discussed in prior tread), but I may need to think more long term. When I'm using the Lee Turret Press I have to move the handle four times and then manually eject the case. I know there is a mod to the classic turret press to change the turret rotation so the case can be automatically ejected and may be something to consider. But there is some expense to that and I still have three extra pulls of the handle for one round. Not a major problem now, but as my needs grow ……

Again I like the way I'm doing it especially the double check of the powder charge (one mechanical through the RCBS Powder Check Die and the other a visual check) and everything is very deliberate and at my pace. I used a full progressive before and never felt fully comfortable. I would consider a Dillon 550b (650 costs too much and too much happening at once) but it only has four stations. Also I have fully loaded Lee Turrets (dies and powder measures) for the 357 and 327 so I would hate to have to buy them again. I know one work around is to seat and crimp at the same station (4) and in my case leave station 1 open but I like seating the bullet and crimping in separate steps. I also like the Lee Factory Crimp Die which I know is a topic in itself.

Since I size and prime off the loading press, can I set up the Dillon 550b press the same way I do the Lee Turret Press using Lee dies and the Lee Auto Drum Powder Measure in Position 1? I know I can't use the Dillon Powder Measure in this configuration because the way powder charging is configured and activated on the Dillon. Lee on the other hand can be activated by the presence of the case alone. I also would not use the Dillon priming feature just the way the cases flow through the press. This would seem to increase speed dramatically without taking me out of my comfort zone, Can this approach work?

I am at this point just trying to explore all alternatives. There is a lot of expertise here on the forum and would appreciate any thoughts or comments.

Thanks!

The one possible problem I can foresee; Would your Lee dies be long enough? If there is not room to place a locking nut on the top of the tool head, Loctite the dies in the tool head without a nut. On the old 450 we would some times use the nut below the die, but the tool head has gaps or hollows that some locking nuts will wobble around on. The "Window" of operation is very tall on a 550b, but you might want to light up the area.

No reason it shouldn't work, as long as you are relying on the spring return for the auto-disk. You can save some money by getting the 550 basic, which comes without a priming gizmo and a powder measure. These could always be added later if you wanted.

BL 550 Basic Loader (15399): Reloading: Reloading Machines at Dillon Precision

There's nothing different about station 1 vs station 2 for your purposes that I can see.

That said I've had a lot of problems with the spring return failing and causing squibs, but I don't inspect like you do. I use a 450 converted to a 550, and have rigged the chain return for the Lee Auto Disk at station 2 on my Dillon. It's solved the problem for me.
 
I never liked the Lee Auto Disk Measure. I used it on a Lee 1000 Press. The measure I'm using now is the Lee Auto Drum Measure (I have two). The Lee Auto Drum is easy to adjust, very flexible in setting charges and throws pretty consistent charges. So far I have been very satisfied.

I wasn't sure if there was any difference on the 550b between station one and others other than priming which I would disable. The only other concern is whether everything fits OK. There seems to be some concern about the length of the Lee dies.

The BL550 does seem to be what I'm looking for if this approach would work.
 
I use Lee dies sometimes in the Dillon and I don't understand the "Length" concern. I do use the riser for the Lee Auto Disk. This will raise it up above any interference from any brand of dies if that's what the concern is.

FS ReLoading - Lee Precision Auto Disk Riser - FS RELOADING

I use the Lee Auto Disk because I prefer a fixed disk measure for a couple of reasons. If Dillon made one, I'd probably buy one. The fact is if you prefer a fixed disk measure that is automatically actuated there's only one choice. If they are the only hubcaps that fit....

Your idea is sound and it will work.

The real question is "Is it is ok to put Volkswagen hub caps on a Mercedes?".

Yes, as long as it takes me to my destination safely, comfortably, reliably and economically. Replacing Mercedes Hub Caps is vey expensive and only adds to the car's eye appeal. More important to invest in the tires. ;)

Your point is well taken though and I wish I could stay with one manufacturer. But I have a lot invested in what I already have and don't want to waste it. Besides the way the 550b is currently configured it is missing one station for a powder check die which I want for my peace of mind.

I do use the riser in my turret press. I think in a turret press its required so everything will fit.

The concern about the length of the dies is from Ivan's response about some issues he had.

...and I've mounted lots of different Lee dies in multiple calibers on both a 450 and a 550 and never had a problem adding a locknut on the top. I confess I don't understand his comment. I don't think the Dillon head is significantly thicker than any other, nor are Lee dies shorter than any other.

If this wasn't standardized across the various platforms nothing would be interchangeable. You'd have the same worry using Lee dies in ANY press other than Lee. Lee dies are just as "long" as anybody else's. I've never run into a problem with dies not fitting across various brands of both dies and presses as long as they were all the 7/8 - 14 standard. I've used Dillon, RCBS, and Lee presses and just about any brand of die. Horandy, Lee, RCBS, Redding and some obsolete names.

Except your 4hole turret is configured the same. I would just buy the 550, but then I look at gear cost diff than most. It's cheap if it saves me time & always works. Current Lee dies work fine on the 550. You may have to use a Dillon lock ring on the bottom if using older Lee dies.
