Neck Trimming Question

[Mr Underbridge]

So I bought a WFT trimmer that goes into a drill, because turning them by hand on an RCBS brass trimming lathe is driving me insane.
WFT Indexes off the shoulder for trimming the length of the brass.
I have a full length redding S bushing die. Can I take out the bushing and size the brass and trim, insert the busing back in and size again. I just don't want to size the neck and trim it, the blade moves pretty fast and I am not sure if it will mess with the shape of the neck.

It should not harm the neck. At least mine doesn't. Just go ahead & trim & chamfer & load!!

ok glad to hear. I get too anala retentive about unnecessary stuff sometimes. Will FL size it along with the neck and trim it. Thanks folks.

Don't size without the bushing...the neck could, and likely will, be 'pushed off' to one side. Because the WFT indexes off the shoulder/neck junction to control trim length you will end up with poor control of that length over a run of cases. There are other reasons you should resize with the bushing in before trimming but I will go Guffey on you and leave you hanging.
