Trim Doctor II Shotshell Trimming Tool
The Trim Doctor tool is two tools in one:
This is a re-designed version of the original Trim Doctor. After years of searching the world for just the right case trimmer without success, our ballistic technicians demanded that BPI make this convenient and necessary tool. An adaptor bushing and gauge plug hold 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 a 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 trim plug.
The key feature of the Trim Doctors redesign is the removal of the adjustable threaded rod. Replacing the threaded rod is the new 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 gauge plug, insert loaded shell through the adaptor bushing 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. What our customers say about this product: "I started roll crimping in 1970 using an old hand crank crimper on Federal paper hulls. I started doing it again just recently due to the availability of straight wall hulls and it is something to do in my retirement. Your Spin Dr. and hull cutter are indispensable." - Paul, AZ

Trim Doctor 2 Update | 10/1/2024 |
This is a re-review to my previous one. I am pleased to report the trim Doctor tool works as advertised. The fault was mine after installing the depth plug/gauge plug backward. After a phone call to Ballistic Products, they reviewed the tool with me and had me reverse the plug. Worked fine easily trimmed the hull removing 1/4 as intended. Moral of story call them back and ask for instructions if something does not work. Summary buy this trim tool you will happy. | ||

Trim Doc II Shell Trimmer - 2 problems make it not work! | 9/22/2024 |
Im sorry to report that this tool does not work. Two major problems : 1. Wont cut thru the shell. I tried 3 different brand shells, Federal, Winchester, Remington. No luck with either it cuts a small groove but wont cut all the way thru. Blade location appears to be too shallow for thru cut. 2. It cuts the shell too long 1/2 cut length increments. Supposed to be 1/4. The stop plug that the shell touches against is too deep. Dont know what happened with the design it looks very well thought out. I operated the tool exactly like the instructions but in the end does not work period. Based on my experience I cannot recommend anyone purchase this tool. | ||

Good for what its for | 7/25/2024 |
Works for trimming one set cut so if you need adjustable you could make shims. A shim kit might be a good accessory. Take the advice of one of the other reviewers and dont force the tool; light pressure all you need. For trimming paper hulls for black powder loading it works great. Also removing star crimp combined with skiving tool is making nice looking roll crimped shells. Minus the one star for adjustability. Good value for sure. | ||

Nifty Little Tool | 2/27/2022 |
I reload a lot of 2.5 shells for 12 gauge. The Trim Doctor II allows me to get perfect straight cuts on any hull with very little effort. I can sit in front of the tv and trim several hundred of my beloved gold medal papers in an evening. Actually makes the chore enjoyable. Thanks Ballistic Products! | ||

More experience with this tool | 2/21/2018 |
Now that I have been working with this tool for a while, I should update my review. I started to have a problem with the cut spiraling. What I learned is this: 1. Dont push down too hard on the top blade of the tool. This makes it hard to turn the shell, and can cause #2. 2. Dont push in too hard on the shell. This can cause the shell to collapse over the cut, making it spiral. I can now reliably produce square and neatly cut shells every time, by following these points. | ||

Good tool, watch out for the blade when its open ! | 1/18/2018 |
Like most devices, this tool is a little tight when new; it just needs to break in, so be patient. As you go, you will learn the technique for good results. The blade is very sharp; I just touched it and started to bleed, so be careful when the tool is open. After a few shells, I was producing good 2 inch shells every time. That takes 3 cuts, since the tool only makes 1/4 inch cuts. For Trim Doctor III, adjustable depth would be great ! | ||

Great tool | 8/25/2016 |
I had tried for years to make my own shell trimming tool, but never got it perfect. This tool form Ballistic Products is outstanding quality, and a good design. I only give it 4 stars because there is little in any way of adjustment. The tool is designed to remove 1/4 at a time, but I find it to be about 5/16 with the bushing fully seated. Another problem is not all shells are made exact. An example is the Fiocchi 3 1/2 shells I am trimming is they actually measure 3 7/16. Not a huge deal, but Im trying to make perfect slug loads. I think a shim kit is needed to make this a perfect 5 stars. I ended up using O-Rings to shim the bushing. 2 full cuts now brings me to exactly a 3 shell. | ||
