Re: Lyman Universal Trimmer question
Your going to run into that problem from time to time,not all resizing/expander balls,RCBS,LYMAN etc. or rods as in the LEE are the exact same size. Then you have the issue of different case wall thicknesses between brands and how it springs back after sizing.
One thing I do is when I insert a case into the chuck I leave it slightly loose when I insert the pilot into the case mouth,then tighten the chuck it helps make sure the case is aligned to the pilot. You might also try if you have any using a little bit of imperial sizing wax on the pilot ever once in awhile what the problem brass. As mentioned above polishing the pilot will probably help also.
As far as trimming pistol brass I usually don't unless it is over length but I usually end up loosing it or wearing it out before that happens,the only pistol brass I have trimmed in awhile is a bunch of 9mm cases I converted to 9 x 18 to shoot in my PA-63. In fact I just purchased a power adapter shaft for my Lyman trimmer to do that with,sure makes the job easier.
