I ran a few numbers based on published data regarding the most common modern manufacturers of factory 30 Mauser and 7.62x25 Tokarev cartridges, because I could not find these comparisons myself. See the attached .PDF file or .JPG. Please let me know if you believe I have made errors, or if I have posted in the wrong location.
I've heard that PPU will be making a High Pressure and a standard version of 7.62x25 Tokarev. It is assumed that this data is for their low pressure standard ammunition.
