Little Crow WFT works very well if you size before trimming. Chuck the trimmer in a drill and clamp the drill to the bench, then just feed the brass in until it stops trimming, give it a twist and you are done. It is sensitive to the position of the shoulder, i accidentally used a different shell holder that was .003" shorter and all my trimmed brass ended up .002" longer this week. not really a problem, i crimp with a Lee Factory crimp and it doesn't care. It will throw shavings around, i made a guard out of schedule 40 PVC, and hook it up to the shop vac. Pick up a drill that can be locked on and has speed adjustment.
