I ran some NATO marked 55 gr FMJ thru my Mini-Mauser this summer and chrono'd the shots, the average for the string was 3950 fps +/-. I don't have the notes in front of me, but that was several 100 fps faster than sporting 55 gr SP's. Believe all ammo was W-W.

No readily apparent pressure signs, but the wide variation and high velocity has convinced me not to to it again. The NATO stuff didn't group so hot either, 3MOA from a rifle that can shoot 1 MOA +/- with the right stuff.
