In External Ballistics - Elevation Part 1, I introduced the concept of error derived from shooting at an angle, and gave you a few practical examples. In this article we will examine the real reason for point of impact shift. In many texts around the web, you'll find one common incorrect explanation of this phenomenon: a simplistic approach derived from the formula used to … [Read more...]
Learning how to become a better long range shooter? Here's the next installment in the external ballistics theory mini series: elevation. When I talked about the vertical component of the trajectory, in Bullet Trajectory Part 1, I touched on firing elevation angle. I mentioned that when there is a firing elevation or depression angle, that is, when you're firing with the barrel … [Read more...]
Want to start loading better ammo? You're going to need a chronograph. In this article I want to look specifically at chronographs and their role in the reloading process. But first, let’s talk a bit about “Power Factor.” Power Factor Put simply, power factor is a measure of the recoil force exerted by a round of ammunition when it is fired. For recoil operated … [Read more...]
In both Bullet Trajectory Part 1 and Part 2, I mentioned how light can act as a variable that affects point of impact. Light doesn't directly affect bullet trajectory, but it changes the way you see the target through the telescopic sight. Essentially, you perceive the target in a different way, e.g., larger or smaller, and/or in a different place, depending on the sun's … [Read more...]
Let's start reloading! In the previous article I looked at some general issues relating to projectiles, but in this article I’ll focus on the various types of projectiles available and the process of selecting a projectile suitable for your specific shooting activity. Projectile Types There are numerous types of projectiles out there, and manufacturers seem to be coming up … [Read more...]
In my last two articles I concentrated on the reloading dies and associated tools needed to complete the 4 reloading tasks outlined in my second article, "What is Reloading?" In the next two articles I want to look at some additional equipment which you may or may not need to undertake your specific reloading activities. Primer Filling & Automatic Primer … [Read more...]
