I'm not sure what some of LEE's parts are made of, particularly on the newer stuff. Maybe my assessment of their stuff is dated. I got the turret press in the early nineties and an O-shaped one not long after - for $20 on some kind of special. Both have been excellent presses for me. I only use the O-press for large decapping sessions and for bullet sizing, so it really does not get much abuse. I have not had a "large decapping session" in years, so it stays quite clean and sees little stress. I no longer form cases either, deferring to some pretty common and mild cartridges.
My most modern LEE press - the Hand-Press:
The interrupted threads in my hand-press look shallow to me. I'm less enamored every time I look at the pieces-parts. It came with a steel insert, which has a 7/8-14 internal thread, which I am thinking about installing permanently with green Loctite and an Allen screw and buying locking rings for each die - ditching the colorful, expensive bushing setup. The portable kit will be intended to load ONE LOAD each (MAYBE two) for the 357 Mag and the 30/30, and NOT in vast quantities, maybe ten to fifty rounds at a time. Screwing dies in and out will not be a major detractor.
The part about that which irks me a bit is that the new bullet-sizing die holder and the on-press priming setup are both the interrupted thread deal - not 7/8-14, so that blows my portable kit priming idea up and will add weight/bulk on bullet-sizing. I have the older on-press priming system, which is just OK. I was hoping to avoid having a separate hand-primer in this kit. Trying to keep it skinny, but more convenient (and quieter) than the Whack-A-Mole outfit.
The little, plastic die-wrench? Not a fan. A leather shoe-lace and a toothbrush handle make a convenient/dual-use "strap-wrench" which works just fine.
I've got a shotgun I need to sell, and once I do that, I will reinvest in some different parts. If someone IS a fan of the breechlock bushings, I'll probably be looking to trade for locking die rings in their place. The threads on THOSE look great, but the threads in the press are a bit pathetic-looking and I don't trust them.
