Hornady Case Prep Trio Power Tool — Compact and Effective

Hornady Case Prep Assistant Trio

Nobody likes to spend hours manually chamfering cases and cleaning primer pockets. There are simple hand tools that will perform these tasks, but the process is time-consuming and tedious after a couple dozen cases. To speed up case prep duties, you can get one of the large, powered case prep centers. These function well, but frankly we didn’t want to give up that much precious space on our reloading bench. One good solution is Hornady’s compact Lock-N-Load Case Prep Trio (item 050160). This triple-threat tool packs a lot of functionality in a small package.

This cleverly-designed powered tool has a small footprint, yet it can perform three tasks as well as much more expensive, tower-style case prep units. The Hornady Case Prep Trio $139.99 at Midsouth, $144.65 at Precision Reloading, and $146.99 on Amazon. We’ve used this machine and it works well. The only negative is that you will get metal shavings on your bench (unlike some of the larger case prep centers). We’ve seen some guys put a small pan under the power head — then you can just dump the shavings out of the pan.

With three active stations, you can chamfer, deburr and clean primer pockets without having to change tools. The Case Prep Trio ships with inside chamfer, outside chamfer, and deburr tools. You can also use the machine with other optional 8/32 threaded accessories such as primer pocket reamers, primer pocket uniformers, and case neck brushes. CLICK HERE to see all tool options. Conveniently, the Case Prep Trio has on-board storage for your tool-heads. User reviews have been very positive.
