Anyone working through a pile of Lake City or other military brass knows the primer crimp is the step that slows everything down. The L.E. Wilson Primer Pocket Reamer in small .175 solves that cleanly by turning your Wilson Case Trimmer into a crimp removal station. It drops into the trimmer the same way a cutter head does, and the precision-ground flutes shear away that intentional deformation around the pocket so you can reprime without a fight.
This is the small (.175) version, built for small rifle primer pockets like you'll find on 5.56mm and M1 Carbine brass. Wilson has been a family-run shop since 1927, and that attention to detail shows up in the knob-style handle. That knob isn't just for grip. It keeps the reamer centered and square to the pocket so it won't distort the case head while you cut, which is a real problem with some lesser crimp tools. The result is a nicely rounded entry that takes a fresh primer every time.
If you're already running a Wilson Case Trimmer, this is an affordable way to add crimp removal to your prep routine without buying a dedicated machine or giving up more bench space. The hardened, ground steel cutter holds its edge through a lot of brass, and reloaders who have tried swagers and hand reamers tend to rank the Wilson near the top for how sharp and simple it is.
Worth being clear here: this tool is made to remove the military crimp, not to uniform your primer pockets. If you want consistent pocket depth across a batch, that's a different tool. For knocking out crimps and getting cases ready to reprime, though, the .175 Wilson does exactly that job and does it well. It's made in the USA and backed by one of the most trusted names in precision reloading gear.
It removes the crimp from the primer pocket on military brass, like 5.56mm and M1 Carbine cases. That crimp is there to hold primers in place under heavy use, and it has to come out before you can seat a fresh primer. The reamer cuts a clean, rounded entry so repriming goes smoothly.
Yes. This reamer is designed to be used in conjunction with the L.E. Wilson Case Trimmer, dropping in much like a cutter head. If you already own a Wilson trimmer, it's an easy and affordable way to add crimp removal to your prep.
No, and that's an important distinction. The .175 reamer is built specifically to remove the military crimp, not to uniform pocket depth. If you want consistent pocket dimensions across a batch, you'll need a dedicated primer pocket uniformer instead.
The .175 is sized for small rifle primer pockets, while the .210 handles large primer pockets. Match the reamer to the brass you're processing. Small rifle cases like 5.56mm take the .175 you're looking at here.
