9mm does last a long time, no doubt, but it's anything in the world but "relatively low pressure." In fact, it's right up there with most all of what we consider high-pressure pistol rounds. That's how the 9mm does so much with it's tiny space.
When I first started shooting and started looking at velocity numbers and bullet weights, I could never understand to look at them side by side why 9mm and .38 Special seemed so close, with the edge going to 9mm. Physically, it didn't make any sense.
All about the pressure, and the confined space that creates the environment for the pressure. 9mm is HOT stuff.
I like to swap brass... and I'm looking for .32 H&R Mag, .327 Fed Mag, .380 Auto and 10mm. If you have some and would like to swap for something else, send me a note!
