TRN Shotshell Hull Vise

TRN Shotshell Hull Vise

If you’re a serious shotshell reloader, chances are you’ve found yourself wishing for an extra pair of hands at one time or another.  Trimming, or roll crimping hulls can be a challenge, even more-so if you’re a perfectionist striving for truly professional looking shells.  For jobs like these, you’re going to want a hull vise. While there are a few different models on the market, I thought today we could take a look at a new entry available for sale at the Reloader’s Network.

Produced via a collaboration between two members of that community including the Loads of Bacon channel, this tool is a great example of what TRN has to offer at a time when larger networks like YouTube are working hard to silence us.


Beginning with the construction, as you’ll see in the video above, the vise is made from just a handful of components including a base plate, a pair of blocks, and a toggle.

Both the base and blocks are made from brushed aluminum, giving them a tremendous amount of strength and rigidity, while also keeping the weight down and eliminating the risk of corrosion.  The fasteners are made from a high-strength steel, and have been hand-ground to ensure they’re perfectly flush with the base.  The toggle appears to be a fairly standard off the shelf variety, and seems quite well suited to the application.

Fit and finish are both excellent; as a tool-maker myself, I feel it’s worth mentioning that virtually every piece of this vise has been painstakingly hand-finished and checked.  Every corner, edge and surface has been filed, polished or ground to remove any burs or sharp points.  The rubber grip surface has been trimmed perfectly flush with the blocks, and the mounting holes have been counter-sunk to remove any burs.  Little steps like this may not sound very impressive, but they make a real difference in the ease of use and comfort when working with a tool.  Steps like these are among the first to be cut by less scrupulous manufacturers if it means they can save a dollar or two per unit on production.  It’s nice to see that wasn’t the case here.

As nice as this vise looks though, what we really need to determine is how well it works.  I’m happy to report you won’t be disappointed.


After bolting the blocks and toggle into place, the vise can then be placed on any flat surface, or even clamped to something like a drill press.  Depending on the gauge or size of your hulls, further adjustments can also be made to the toggle block in order to allow for larger or smaller diameters.


Once everything’s set, the operator simply drops a hull into place, and actuates the toggle.  At this point the shell is now locked firmly into place, providing a stable and level working surface ideal for operations such as roll crimping or hull trimming.

As you’ll see in the video above, even when I actively tried to wrench the hull left or right I was unable to do so.  After testing with a variety of hulls including high and low brass as well as smooth and textured surfaces, it quickly became apparent none of these would present a problem.


TRN’s Shotshell Hull Vise is another solid addition to the shotgunner’s reloading bench.  In the past I’ve heard some folks describe hull vises as ‘luxury’ items, but load roll-crimped shells or slugs in any kind of volume and I can assure you you’ll change your mind in a hurry.  Moreover, at a retail price of $50USD (as of this article’s publication date); it’s also a tool anyone can afford.
