Does the RCBS trim pro cut necks square?

[TheCoyote]

I just bought a RCBS Trim Pro 2.
Looked like a great setup, very similar to other designs.
I have trimmed a few cases and when I rotate them in the caliper I get slightly different length measurements.
Not a lot, maybe .0015 - .0025...

I am curious if that is as good as it gets with this thing? Am I using it wrong? Anyone have any experience?

And how much difference does it make to accuracy? If the necks aren't perfectly square does it matter?

Great question - I don't know the answer, but I can say that I own two of them (one is a trim pro and one is a trim pro 2). I find inconsistent cutting anytime I use the 3-way cutters. Results do improve if I'm super careful about how its holding the case for trimming. Maybe I should go back and experiment more with the standard cutters... I also have a Little Crow Gunworks WFT and do find that does a very good job - but it also has its own drawbacks. I haven't found an option that I'm totally happy with yet.

Mine did not. It also gouged the inside of the case neck
RCBS sent a replacement unit and I sold it NIB to a buddy and got a Henderson.
