My taste runs more to a 650. Or 4 of them, to be exact. But I don't want to dedicate a month's pay and a room to the setup. I like the idea of several of these dedicated to my high-volume loads, especially as I have Lee dies and powder measures from the LCT. But I'm not going first - this thing will have to prove itself before I care how cheap it is or how many I might buy. I gather Pro 1000 owners aren't universally happy..

Yes, they fit back in the rectangular boxes. They don't fit in the cylindrical boxes.

Okay, thanks! I figured that is something that it should be brought up, as I would like to know where I'm going to put my dies once I've moved on to a different cartridge.
 
The new Pro 4000

90900.jpg

We have asked for 4 station progressive press and looks like Lee Precision delivered with new features and features from their other presses (Code name "Pro 4000"):
  • 4 stations allow separate seat and crimp operation
  • Auto Index Progressive for high volume operation (Disable auto index for single stage operation)
  • Breech Lock with built-in lock ring for quick no-adjustment die change (4 comes with press)
  • New case feeder design
  • Through ram primer disposal and tube (No more pesky primers and ram/press stays cleaner)
  • Large and small Safety Prime (No more primer feed attachment issues)
  • Ergonomic roller handle (Allows left or right hand operation)
  • Built-in storage rack with included hex wrench
Definitely looking forward to testing the new Pro 4000.

We have asked for 4 station progressive press based on Classic Turret and looks like Lee Precision delivered with features from other presses (Code name "Pro 4000"):
  • 4 stations allow separate seat and crimp operation
  • Auto Index Progressive for high volume operation (Disable auto index for single stage operation)
  • Breech Lock with built-in lock ring for quick no-adjustment die change (4 comes with press)
  • New case feeder design
  • Through ram primer disposal and tube (No more pesky primers and ram/press stays cleaner)
  • Large and small Safety Prime (No more primer feed attachment issues)
  • Ergonomic roller handle (Allows left or right hand operation)
  • Built-in storage rack with included hex wrench
With case collator (and drilled penny and 22LR spent case mod for 9mm/380 cases) and new case feeder design, this new 4 station progressive press has potential for serious volume reloading (pistol and short rifle calibers).

With off-set ram under Station 1, looks like Lee Precision may have worked on reducing shellplate tilt issue when resizing overly expanded brass for more consistent OAL/COL variance. (See last detail picture below). Most progressive presses mount ram in the center of shellplate and during resizing, depending on the force required to resize the brass in Station 1, shellplate tilt can contribute to OAL variance on bullet seat/crimp stations 3/4 or 4/5 depening on 4 or 5 station press. For this reason, I used separately resized brass for my USPSA match loads for more consistent OAL variance.

Definitely looking forward to testing the new Pro 4000.

Left or right side mounting of ergo roller handle. Off-set ram under Station 1 (right front) to address shellplate tilt when sizing overly expanded brass and produce more consistent finished OAL/COL.

Dang nice schematics

Is this classified as Corporate Espionage??:):)

It's by Andy Lee dated 1/4/18.

Off-set ram design under the resizing die looks like it was intended to reduce shellplate tilt for more consistent OAL/COL.

We have to wait to measure finished rounds' dimensional consistencies but Pro 4000 looks promising.

Yes, if you're talking about the flat cases.

Those dies look like they are really closely spaced.

I'd also like to see how crowded it gets when you add the case feeder

That is one thing I dont like about the LCT press, the dies are too close too get a redding type wrench on them. Its not the end of the world, but one of these days I will get that Redding T7.....LCT rocks on for now. For price of entry its tough not to like.

I’ve got one on backorder at Midsouth. For $106 it’s a new toy to play with. IIRC I ordered the plate for 38/357. Also have enough Lee stuff around the reloading room to further outfit the press. Breechlocks and all. Think I’ll make a video of it while mounted next to my XL650. I’m more of a press fan than a brand fan. Machines are just fun and reloading machines are easy fun.
 
What I really want/need to know is about the breech lock bushings?
I do not have the fancy lock rings just the bushings that are held in by the little push button thing.(have a lot of them and would not want to buy the lock rings)

Will the press work or accept the regular bushings? I do not see the push button lock on each hole?

Guess will need to wait to see the actual press

The bushings with and without the cross lock ring are basically the same, except that one has a lock ring attached. Both are held in the regular breech press by a push button thing. So the regular bushing with your choice of lock ring will work. There is no button on the press, but I think the bushing will not rotate with use. Hornady LNL bushings do not have a button lock.

Yes, that is what I am thinking also, So I would have to buy the lock rings to use my bushings. Cha Ching$$:)
I have a lot of bushings:what:
 
FWIW, the newest C style press from Lee uses the breechlock inserts, but it does NOT have the push button lock. The insert does drop in, and about 1/3 turn tightens it into place.
 
Tool head without the bushings

Tool head with bushings (with and without lock ring). No lock button on the cut out but I don't think the bushing will rotate with use.

Don't you already have lock rings on the dies?
Click to expand...

Yes, but they are what lock the die setting in the bushing, not what locks the bushing into the press. That is why I linked the LEE breech lock video which shows how the bushings lock in (with the pop up button)

Oh well I am concerning myself with something that is not even here yet, we shall see,

Then why would you have posted:

Lee has obviously decided that the Breechlock bushings don't need the button to keep them from rotating...or that the occurrence of that happening is so small that they would do what Hornady does and send you a shim or O-ring to tighten the fit
 
They show all the bushing cut-outs towards the center, and I am wondering what the slot and hole in the center of the tool head are for. Could be there is one ring that drops in the center that fits the bushing cut-outs, locking them all in place at once.
 
I see stamped linkage and I’m out. It does beg the question though if Lee is going to retool the entire product line in the near future because there are new versions of just about everything coming to market. I seriously considered the “value 4 hole turret” over the classic turret but it’s new enough that the price is still almost msrp. Now the question to me is, if they are making changes is it intended to cut production costs or is it to improve a product.
