Dillon Precision trim dies are used just like a standard size die. The big difference is that while you are pushing the case into the die to size it, a 1/4 horsepower electric motor driving a carbide cutter is trimming the case to length. Trim dies, in all calibers, are compatible with both the older RT1200 Trimmer as well as the current RT1500 Trimmer.

Trim dies include the lower die lock ring. Upper die lock rings are not included with the trim die, but are available separately.
