I heard that Dillon paid Lee for the rights to use their auto powder measure design for their powder drop die and powder measure.
The Load Master press itself is pretty convincing, as long as you don't try and run everything at once on it. Maybe small pistol calibers you could, but .45 Colt is a big case, and it takes a LOT of effort to resize it, seat primers, boolits, and crimp. You need the arms of Mike Tyson to use it in a full progressive mode on large pistol ammo.
For .45 Colt, I have always liked their crimp dies, I think the resizing die squashes the sh!t out of the case and it's tighter than necessary but I learned a trick with that. Use the universal decapper instead of the recommended sizing/decapping die, then take a Factory Crimp die apart and use the die body for a sizing die in the priming station. What that does is take half the effort to resize the case, and it doesn't wasp-waist it, and it will serve as a guide to hold the case in perfect alignment for the primer seating part of it. Works great!
I use their roll crimp/bullet seating die to seat the bullet and remove the flare at the neck from the expander, then I crimp with the uncataloged collet type factory crimp die. 3 crimp dies in one operation? Yep, works very nicely. Oh yeah I did modify the collet crimp die, I shortened the crimp ring to narrow the crimp band on the case mouth, and I shortened the bottom of the collet to bring the crimp band down just slightly below the case mouth, it now looks like Buffalo Bore crimped it
Also I cannot recommend priming on the press while using a crimp die that the shell holder activates such as the collet die, you can easily have a situation where that crimp die prevents the primer from seating fully. The Load Master's priming function is GREAT when you use a die as mentioned to hold the case for priming, and set the press up to *just* prime cases, and kick them out the side, then take the primer feed completely off and run it in progressive stages using the primed brass.
Their newer powder measures have issues. Bad issues. Mine throws powder all over the place, is staticy as all hell, very hard to get consistent charges, and the rubber insert is all torn up, with less than 100rds on it. I have since backed up and punted, ordering a Dillon powder measure with their die and powder funnel. I had an old auto-disk setup with an adjustable charge bar that was really good, this new one is a ***.
Other than learning to prime as a dedicated single function, and getting a better powder measure, it works good enough for what it cost me.
