I have been collecting data on performance of various calibers… Mostly 9mm, 380 acp, 32 acp, 5.56 and 308 winchester. I collect velocity, weight of projectile, powder charge, total cartridge weight and accuracy… Although i know accuracy is somewhat subjective. I have collected a bit of data already and i would occasionally like to post this information… If anyone would like to see it. I tend to only test surplus or what i find unique. If there is a place here to post this and if people want to see it, i am willing to share it. Most of my data is for 9mm. Hopefully someone can shed some light on this question. Thanks.
