We (well, Jim K, Once all the ammo was tested at 18″, one inch of barrel was chopped off, and the tests repeated. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. They established protocols for testing using two chronographs in which three shots of a given ammo for a given caliber were tested at 18″. here to get an idea of what to expect, and perhaps as a jumping-off point for your own research.

Unprepared Adults Lead Scary Camping Adventure; Unprepared Base Camp Hiking data is provided purely for entertainment purposes - to better facilitate arguments The purpose was to determine velocities at this length, and every inch shorter down to the practical minimum length of 10". A fast hand loaded 150 grain bullet creates a lung wound less than a quarter inch larger than typical factory loads with exit wounds averaging .75” as opposed to just under or around .5” for factory loads. the firearms community. Although the difference in exit wounding may seem small, bleeding from exit wounds as a result of full velocity hand loads is … Some ammunition maxes out sooner than others in the same caliber. Or not. Welcome to Ballistics By The Inch, or 'BBTI' as people have taken to calling it. involving more than 6,000 rounds fired, as well as a comparison of the performance differences Only the biggest public database of how ballistic performance drops off over barrel length for 16 popular handgun calibers. meant to be indicative - giving an indication to the general relationships between barrel length It started with a question that has fueled countless discussions over the years: does size matter?
