A while ago I bought from Marstar, 5K a berdan prime and 3K of boxer prime.
I don't keep my empties but as far as performance go the berdan prime are more accurate in my M1A and my FNAR rifle, not by much but they are more accurate so if I have the choice I will take the berdan prime over the boxer prime.
They also are more rapid around a hundred feet per second more rapid than the boxer.
