## Description

The Hornady primer pocket reamer replacement cutter head makes cases with crimped primer pockets reloadable by cutting away the crimp. Heads also fit on Power Case Prep Center and Case Prep Trio. Extra reamer head only.

Review: removes factory 5.56 crimp and lasts well - I bought one of these small primer pocket reamers by Lyman and it didn't even make it though 50 cases before losing a significant part of its cutting ability, and eventually all. The Hornady version so far has been much more durable and worked very well. As others have mentioned, it can easily be chucked in a drill (I chuck the larger diameter, not the threaded part). Update: This primer pocket reamer and processed many hundreds of cases by now and is still working well. I did modify it slightly: I wanted it to cut a bit more of a cone shape where the crimp was and also didn't want it to remove any material from the bottom of the primer pocket. I used a sanding disk to remove a very small amount of the cutter where it touches the base of the primer pocket and it does exactly what I want it to do now.
Review: Works great for .223 - I mounted this to a Dewalt drill.. Just a quick second tap on the trigger is all it takes to clean the primer pocket. I bought some once fired brass that was military recycled. It has a "primer crimp." That means unless you cut out or "swage" the pocket when you try to replace the primer it will get jammed up and not seat properly. This tool cuts great. Just a tap is all you need. If you go too much and your primer doesn't "feel" right seating. Toss that one away, you cut too much. I cut much to deep on the first try and the primer fit in so easy I knew it was too loose. It is an art so get the feel for it and away you go. Also keep track of what brass you already cut the crimps out of. You wouldn't want to cut the same piece of brass a second time. It might get too loose in the pocket and your primer will fall out. You can see the crimp if you flip over the brass and have good eyesight.

### ⭐⭐⭐⭐⭐ removes factory 5.56 crimp and lasts well
*by R***Y on September 4, 2022*

### ⭐⭐⭐⭐⭐ Hornady reamer fits in the RCBS Case Mate.
*by G***7 on October 20, 2013*

Since receiving this reamer I have processed approximately 150 5.56 NATO brass, mostly as an experiment as to its' function, value and quality. I use the RCBS case mate for my cartridge processing and the hornady reamer threads into the work station just fine. The threads are actually too long and once threaded into the RCBS case mate some threads remain exposed. This did not hinder the performance of the reamer and the primer crimps were removed effortlessly. Very little pressure is required to remove the old crimp in the brass I tried (mostly Lake City and WCC). One could use a piece of brake line tubing or something similar to shim the exposed threads if a recurring problem presented itself with the RCBS. I have not encountered such a situation to this point. Furthermore, the reamer is very sharp and machined even better than I was anticipating. I am pleased with its' performance thus far. Time will tell about longevity, but I have no concerns thus far. Bottom line is that this reamer works very well and it fits into another brands tool (RCBS). Happy reaming.
