I tried recently to trim some .44 mag and 9mm brass. The .44 brass was sized by myself and someone else and both of us ussed RCBS carbide dies. trimmed the 9mm brass again using RCBS carbide dies.
When I tried to trim the brass, the pilots for the trimmer were EXTREMELY tight in the brass. So much so that trimming wasn't really possible. I had to remove the pilot from the trimmer to get a better grip on things to be able to get the pilot out of the brass. My trimmer is a Forster and I also tried a new RCBS.
Any ideas what I did wrong and why the ID of the brass is too small for the trimmer pilot? I checked and double checked the pilot charts for both the Forster and RCBS trimmers to make sure I was using the correct pilot. When I queried Forster for the problem with the .44 mag brass, they suggested I send a couple of cases as well as the pilot and they would machine the pilot down to match the brass. I'm thinking that's something I don't want to do as the tooling (sizing dies and trimmer pilots) should be a standard dimension.
The brass is mixed mfg. I've measured the ID of the brass and the OD of the trimmer pilot and it measures just as you would expect with the tight fit, so I don't think it'san alignment issue with the trimmer.
Thanks for your help...
