the hungarian that i have shot over the chrono is as follows:
the yellow tip stuff, 21 over 51 headstamp ==>2525fps
the stuff on stripper clips, 21 over 52 headstamp ==>2750fps
by comparison, the S&B 180 grain softpoint does 2550fps
all of this is out of a polish M44 with the 20" barrel, so velocities should be higher out of a long rifle.
