Forster outside neck trimmer issue

[kelbro]

Have used Forster HOT100 for years on 223 and 257 without an issue. Just bought new pilots for 243 and 308 and cannot even force the brass onto the pilot.

I doubt that Forster has oversized pilots in two different calibers.

Standard dies (no bushings). Can't even fit new, unsized brass.

Are the expander balls too small?

What I ended up doing because of the different neck thickness was to sand the pilots in a drill with some sandpaper till they just fit. With all the cal. I reload, I just started making my own pilots.

Well I took a stab at it from another angle. Used the Lee Collet die and then was able to get the pilot started. Found out that there was a very slight burr on the leading edge of the pilot. A little emery cloth and now they fit like they should.

I can trim Lapua with NO problems, BHA match brass, no problem.

Try Federal, NO way, I am sure some of the suggestions above will help, but I only use Lapua now and don't have a problem.

Cool discovery. The necks on these two batches of Winchester brass were nearly perfect. I'm usually not so lucky.
