A trimmer that also works with cases that don't have shoulders?...

Same here. And if I do my part, it will trim brass amazingly consistently (measured with micrometer). I never trusted the Lee trimmers that go down through the neck, the web thickness on brass is very inconsistent. Are they easier to use? Absolutely! And much faster, too! But you wind up with brass of inconsistent lengths in your batch for reloading. For blasting ammo that's not a problem, but if you want accurate ammo it may be an issue.I've been using a Lyman trimmer for decades, and don't think I"ll change.

44Amp,The recommended trim to length is just that, a recommendation, not any kind of hard and fast rule. It's simply a length shorter than case length max, and a point chosen for convenience as much as anything else.
For most rifle rounds its 0.01" below max case length. This is a point where usually the case can be loaded several times before growing back to max length and needing to be trimmed again.
Look in a Lyman manual, and you can find cartridges where the recommended trim length is half the usual .01" or even less. particularly pistol rounds.
The recommended trim for .357, .44 Mag and .45 Colt is NOT 0.010" it is 0.005" and the trim for 9mm and .45acp is 0.003".
There is nothing magic or specially significant about trimming 0.010" its just a handy spot for rifle rounds.
guidelines...NOT rules....
Touché.A trimmer that also works with cases that don't have shoulders?...
My method is unorthodox but works for me, In anything but my bench rest rifles anyway. I trim it before I size it. Use RCBS trimmer. Always within a thousandth after sized.Case Trimming, Yes I know its everyone’s favorite thing to do in brass prep.
I wanted to bring this up too see if anyone else has had this issue,
I noticed if I trim based off the shoulder of the cartridge its no where near as consistent than if I use my $3.00 lee trim cutter head with a caliber specific shank and shell holder.
I have trimmed thousands of cases with the lee and honestly its so consistent its hard to believe. it trims every case with in less of half of 1 thousandths. But it takes forever. Even using a drill having to chuck every case in the shell holder is painstaking.
Even my hornady case trimmer doesnt get it as consistent as the lee. Was wondering if anyone has noticed trimming off the shoulder is not as consistent.
I do anneal my cases every time and when I resize i count to 10 before i remove the sized case to help reduce spring back
But I have to admit it has been a long, long time since I've trimmed straight wall cases.
They do say if you run it thru the case thru the m die that it will deburr and that when you wet tumble it will smooth the case necks out
I don't wet tumble, so can't say what it does or doesn't do.
Can tell you the M die does not touch the outside of the case at all. So it can't de-bur the outside of the case mouth.
the two step expander will push burrs inside flat, and can be adjusted to flare the case mouth, but its not the same as a chamfer tool cutting a bevel.
They are costly...and moreso these days but the Hornady Lock-N-Load Power Case Prep Center should work for any type of case. I recently acquired a used one for about half price, but I haven't used it yet...preparing to trim some 224 Valkyrie cases shortly.A trimmer that also works with cases that don't have shoulders?...

Nick,The Giraud has case holders for both rimmed and rimless straight cases (the pistol magnums and 30 Carbine) but I don't have any of them, so I can't say how they work. I've never needed to trim enough of those cases at one time to justify the investment. I should call and ask how they work, though.
