Here are some of my recent tests out of a Glock 17 (4.5" barrel) and a Kel-Tec Sub 2000 carbine (16.1" barrel). I used the Kel-Tec because I was curious to see how much velocity would be gained by a longer barrel with the various ammo that I tested. Everyone has a theory but, one test is worth a thousand theories.
If it matters, testing conditions were about 40 degrees farenheit. All testing was done on the same day.
I am by no means an authority on ballistics. I welcome all feedback and comments.
