In this article, we’re digging into terminal ballistics: the science of what happens when the bullet impacts a target. In particular, we’re going over the history of the research and what we know today about how bullets wound and kill a target.
Most field shooters, from big game hunters to military members, do not have the luxury of time to check distance, adjust sights, and take a precisely aimed shot. Knowing and using the point blank zero is a tool for helping with that.
Let’s talk about twist rates.
Specifically, I want to dig into the purpose of rifling and how to determine the right twist rate for your rifle and cartridge.
There’s a lot of engineering voodoo that goes into making a rifle work well and fire accurately. The length of a rifle’s barrel and how it affects the velocity of the bullet is one of those major factors.
In 1950, Donald Hall sought to explore alternatives to the full-sized battle rifle cartridge. He built upon R.H. Kent’s work decades earlier, and found similar conclusions that challenged Army thought.
The Swiss Sniping 4th Generation, or S4G, concept leverages ballistic arcs and volleys of fire to increase hit probability. It’s not as fancy as the American Designated Marksman Program, but it’s no slouch, either.
