After several hundred cases being prepped over last couple weeks my hands/fingers had enough. Read up on the RCBS, Lyman, Hornady, Frankford Arsenal case prep stations and decided to go with the Frankford Arsenal with 4 station heads. The ability to sit station vertical or horizontal was a big plus. They all seem to have few bad reviews about some having a little wobble in one or more station heads. Got mine and found one head is true enough for any case prep operation, so I used it for military crimp removal. The other two are plenty good enough for inside/outside case mouth deburring. The case trimmer does (bottle neck cases only) and works great so far. Have only trimmed and removed primer crimp 700 223 rem cases, 100 221 FB cases. After a little use I can repeat trim length easier than my manual RCBS trimmer.
