The BPI Trim Doctor II is a redesigned version of the original Trim Doctor. After years of searching the world for just the right case trimmer without success, the ballistic technicians at BPI made this convenient and necessary tool. A threaded adjustment gauge in the Trim Doctor II holds shells in alignment to produce a clean and crimpable edge. The Trim Doctor II is designed to remove 1/4" at a time (about the same as full fold crimp): 3" shells become 2-3/4", 2-3/4" become 2-1/2". Two full cuts on a 10 gauge shell produce a 2-7/8" shell. Select the gauge of your new Trim Doctor II; it comes with one gauge adaptor bushing and the new trim plug. The ExactaTrim adaptor bushings assure tight cuts with no spiraling and they are available in additional sizes to make your Trim Doctor II even more versatile.
The key feature of the Trim Doctors redesign is the removal of the adjustable threaded rod. Replacing the threaded rod is the gauge specific Trim Plug system. Each individual gauge now has its own unique plug that can fully support the interior of the hull during the trimming process. This design allows for the addition of previously incompatible small bore gauges, while also providing for much more even and consistent cuts by removing the threads. Handloaders who have previously purchased the older versions of the Trim Doctor can easily upgrade their tool by purchasing the new Trim Plugs.
As a shell disassembly tool, the Trim Doctor works on any gauge, 10ga through .410. Just remove the threaded guide, insert loaded shell into opening and gently turn the shell while applying slight pressure to the blade guide. The top of shell will pop off cleanly after a few turns. The Trim Doctor will pay for itself many times over by allowing you to retrieve components from reject shells and by allowing further firings out of many hulls with tired crimps.
