I currently use the Lee case length gauge and shell holder style case trimmers and it is very time consuming and you can only trim to the one set length. I am looking for something to make my brass trimming and prep much faster and the ability to trim at different lengths. I have been looking at the Giraud, Trim It 2, and PMA trimmers but don't want to have to buy separate trimmers or adapters for each caliber that I have. I have also been looking at the Lyman Trim Xpress, Frankford Arsenal Universal case trimmer, and the Frankford Arsenal case trim and prep center. They all 3 appear to trim using the same concept as the other 3 mentioned earlier by trimming off the shoulder and they look like they come with everything for multiple calibers. Does anyone have any experience with the Lyman or either Frankford Arsenal trimmers? The Lyman and FA universal trimmers look like they are new and haven't been out very long. I would also get a simple case prep center with chamfer, debur, and primer pocket cleaner if I went with the Lyman or FA universal trimmer. Thank you for any advise.
