## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by S***S on November 12, 2024*

Works as expected from RCBS.

### ⭐⭐⭐⭐⭐ Better Than The Lyman
*by A***N on October 24, 2013*

I bought this to use on the Lyman Case Express unit (which I REALLY like). I had been using the Lyman Primer Pocket Uniformer to process .223/5.56 and was reasonably satisfied until I saw this one. The difference is that the RCBS has two relief grooves that allow the trimmings from the pocket to fall out of the pocket as it is uniformed while the Lyman has none. So with the Lyman you must constantly watch that no debris is on the surface beside the cutter that would prevent the casing from fully seating on the cutter which would not allow the cutter to go to the full depth of the pocket which defeats the purpose of uniforming the pocket.I have not yet compared how well primers seat but I have not noticed that the RCBS fits snugger in the pockets than the Lyman uniformer which I am assuming is better but I may be wrong.The RCBS uniformer has the same threads as the Lyman so easy to mix these.I like it so much that I also ordered the RCBS Large Pocket Uniformer.

### ⭐⭐⭐⭐⭐ Fast delivery
*by A***. on August 25, 2025*

Works as it should. Just what I needed.
