As before, we’re setting the way-back machine to the early 1950s and the dawn of the atomic age. Once again, I want to acknowledge the work of historian Daniel Watters, whose 5.56 timeline lives [Read Full Article »]
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 this post, I explain a bit of the physics involved here. But the real meat of the post is comparing three different barrel lengths, their ballistic trajectories, and how it might affect what zero you choose. [Read Full Article »]
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 bit of math here, but I promise to give you an “easy button” by the end.
So let’s get to it. [Read Full Article »]
The Swiss recognized the same need as everyone else. They needed infantry capable of using precision rifle fire at range. But they didn’t have the time or budget to do it the same way as other military powers who stood up designated marksman programs. Instead, they developed a system that mixed a point blank zero with designated holdover points and controlled rapid fire instead of single shots. The called this concept Sniping 4th Generation, or S4G. [Read Full Article »]
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. In the real world, targets don’t want to be shot and they won’t expose themselves long enough for you to go through all those steps. So the challenge for the shooter is balancing accuracy requirements against available time.
The Point Blank Zero is one of the most important methods for doing this. [Read Full Article »]
