Gen II PMA Micro Adjust Trimmer

We've updated our Micro-Adjust Case Trimmer to a more compact size, and added a removable hex drive unit. The second generation Micro-Adjust Trimmer is over an inch shorter, but maintains the spring loaded tool head and easily adjustable trim length of the original.

The PMA Micro-Adjust Case Trimmer will trim nearly any bottleneck cartridge you can throw at it. Our trimmer indexes case length off of the shoulder of a properly fire-formed and full length re-sized case. We accomplish this through the use of interchangeable Delrin™ inserts which capture the shoulder and neck of the case. This insert is contained in a spring loaded tool head that rides on a linear bearing. When the case is captured within the tool head the tool head rotates along with the case, the spring allows for the case to self-align squarely to the cutter and allows you to control the feed rate into the cutter.

Features:

• Indexes off shoulder for easy, consistent trim length
• Fully rotating head with bearing for smooth operation keeps cuts square
• 1/4" hex drive for use with power screwdriver quick detach 1/4" drive or chuck into a drill
  
• Sharp carbide cutter for quick, smooth cuts with minimal bur
• Cases captured in Delrin™ (a completely non-marring material)
• Spring loaded head allows complete control of rate of feed.

The trimmer includes one cartridge family specific insert. Please choose from the table below and the drop down menu below that when ordering.

If you have a custom chamber and desire the best possible insert to cartridge fit, select the "Blank Insert" ("P") and ream the insert using the same custom reamer as your rifle's chamber. Blank Inserts have a 1/4" pilot hole pre-bored.
