WFT Trimmer

[waho]

Question for the guy's using the WFT. Are you getting consistent length's? Out of 20 shells 5 were short by about .020, the rest varied about +/-.002 . These were all the same head stamp. Trimming was done after cleaning.

So all of these were re-sized, cleaned and trimmed at the same time? I only find differences like above when I have different head stamps. If they were re-sized at different times there could be slight differences in the setup of the sizer then and now.

I have done a few hundred 308 cases (all resized at the same time) and have all been within +/-.001

Maybe metal particles on the cutter? Make sure it is tightened well also.

It's probably cause by sizing stage. Do you have a headspace gauge?

I would size 10 pieces of brass. Make sure they all have the same headspace measurement. Then trim and compare the OAL case length.

from Giruaud: Also trims case based on headspace:


Next, check your overall length of the
trimmed case with a caliper. I will set
the length fairly close, but it will really
depend on how you size your brass.
Since the case trimmer locates each
case by the case shoulder, if your
headspace dimensions on the resized
brass are not consistent, then the
case can't be trimmed to a uniform
dimension.

All checked after chamfer/debur?

[pisarski]

did you trim them before or after sizing the cases ???
if you trimed before that is why

They were cleaned, sized, cleaned and then trimmed.
