Pre-WWII german ammo is not really available anymore, while M75 goes for .40 cents a piece on SPG. Any side by side tests i have seen between M75 yugo and 1930's german heavy ball(someone on the boards posted it) only saw observable performance differences 800+ yards out. 70's yugo is only slightly behind 90's yugo (M75) in performance.The M75 is xlnt surplus, but def. not match ammo. My German P635 from 1939 shot the pants off it.
