I have shot a whole bunch of the 168 and some of the 175 FGMM. Through every gun I used over the years, (my own and several county issued rifles) it became apparent to me why it is considered the best commonly available precision rifle round. I don't think I have ever heard a bad word about it, other than when an LE sniper used it in an LE sniper application, and was disappointed in the results.
I have never seen anything less than relatively shiny rounds when new, or even packed away for a few years. I have also never really had any problems reloading it, as others claim the primer holes are "soft".
