Put together this video comparing the power of two loads (one is PPU commercial, the other Soviet military surplus) to see if there's really much difference using my foolproof ballistic test. The end result seems to suggest there's indeed quite a difference but it seems as though further testing may be necessary. Curious as to thoughts!
