I have Lee 'Turret' (tool head) presses next to my auto-indexing progressives, they are just WAY too handy for tooling, taking down QC loads/fails (no 'Mystery' rounds laying on the bench ever).
While the tool head does move up/down, it doesn't 'Tip' side to side/front and back.
The ram can go what ever direction when it deflects...
I hear the guys with concentricity gauges complain, but they are blaming the wrong part of the press.
I know guys like their toys, but to be honest, the only thing the neck of the case does is hold the bullet mostly centered with the bore.
When you show them the difference in the throat, where the lands of the rifling meet the bullet when it's fired, and the lands have more difference than the case/bullet out of common loader/dies, sometimes they connect the dots, sometimes they don't.
That bullet slamming into a slanted throat has way more to do with things than the bullet being slightly askew in the case AT REST...
Most presses will produce reasonable ammo with a reasonable die. That's why there are so many brands/colors.
If one worked above all others every time, that would be the design everyone jumped to.
Slow, stout so it beats the brass everytime,
Or faster/lighter/cheaper with a little less consistency.
Keep in mind, this is a punch press that bends brass...
When you look at industrial metal presses, they are always 'Chunky', overbuilt, and never aluminum.
They have to beat the brass every time, so overbuilt is good.
They have to live for decades, in some cases running 24/7 so they are steel or iron, cast aluminum stresses & fractures over time, use cycles.
When it's steel on aluminum, the aluminum always looses, so clean & lubricate so the aluminum doesn't wear like crazy.
(Lee owners, take note, the gray 'Slurry' that collects up on the ram is abrasive, liquid sand paper, clean it off and lubricate!)
I can, and have put a bronze sleeve in the older, worn presses, but that costs nearly as much as the press did new, and the way to avoid it is simply cleaning and lubrication.
With cleaning & lubrication even a Lee aluminum body press will last decades (depending on use, it's not an industrial unit).
It's the upper fame where I don't much want cast aluminum.
Even Dillon heavy 'O' frame presses break, there are several warnings about trying to swage primer pockets or bullets on Dillon aluminum fame presses.
If you are going to swage, get a swaging press... The correct tool for that job.
