Lee Precision 300 AAC BLACKOUT CASE LENGTH GAUGE & HOLDER

The simplest way to check the case and trim to the correct safe length is with a Lee Case Trimmer. After a case has been loaded a few times, it will stretch beyond maximum length and must be trimmed. The Cutter and Lock Stud (sold separately) works for all calibers. The Case Length Gauge (Pilot) and Shell Holder must be ordered for each caliber. Trim cases by hand or electrically. Can be used with an elecrtric drill to trim, chamfer and polish cases faster. Eliminates danger of long cases. Squares the mouth for more accurate bullet seating and exit. Includes Case Length Gauge and Shellholder only.
