Finish Out of PRB’s 100 Yard Underground Range

Finish Out of PRB's 100 Yard Underground Range

A ton of people have asked me for an update on my 100-yard underground range that I recently built. I published an article a couple of years ago that shared my plans and what I’d done so far, and I asked my readers for input on how to finish it out. I changed quite a bit based on those comments. This article will give you a complete walk-through of what it’s like today. Now that it’s up and running, I’d love to hear your suggestions for experiments I should run! Please leave your ideas in the comments!

6.5 Creedmoor Ammo Test Part 3: Live-Fire Muzzle Velocity & Consistency Summary

6.5 Creedmoor Muzzle Velocity

Welcome to Part 3 of the results of a massive 6.5 Creedmoor ammo field test, where I tested multiple boxes of every kind of 6.5 Creedmoor ammo that is marketed as “match” or “target” grade. That included 19 different brands and types of 6.5 Creedmoor ammo! This article is going to cover all the muzzle velocity data that I collected over almost 1,000 rounds fired. Consistent muzzle velocity is key for long-range shooting, otherwise, bullets that leave the muzzle faster than normal could miss high, or bullets that leave the muzzle slower could miss low. While the goal is for ...

Muzzle Velocity Stats – Statistics for Shooters Part 2

Muzzle Velocity Statistics for Shooters

Part 2 in my Statistics for Shooters 3-part series focuses on how to analyze muzzle velocity consistency, which is critical for us as long-range shooters. This article shows how to apply the concepts from Part 1 to get more insight and make better decisions related to muzzle velocity. It provides practical answers to some age-old questions: Should we look at ES or SD? How many shots do we need to fire in a string? How do we get the most value from the shots we fire at the range? I spent an absurd amount of time arduously crafting this article and creating visuals so it was approachable by shooters who aren’t math nerds because I firmly believe these concepts can help a TON of people in the long-range community.

Extreme Long Range Tips 3: Ballistics & Time of Flight

When you extend shots into extreme ranges (like 2000+ yards), you’ll face some new obstacles. A few factors that could be safely ignored inside of 1000 yards become critical to getting rounds on target. You’ll face new equipment challenges that may not be obvious. As your bullet’s time of flight extends up 3 seconds, and possibly even up to 6+ seconds, priorities shift. In this series of posts I’m trying to highlight a few things that make extreme long range (ELR) challenging, and pointing out a few products worth checking out that might help. In the first post in this ...

Powder Temp Stability: Hodgdon Extreme vs. IMR Enduron

Gun Powder Temperature Stability Hodgdon Extreme H4350 Varget IMR Enduron 4451 4166

The goal of this field test was to quantify the temperature stability of the popular Hodgdon H4350 and Varget powders and compare those to IMR’s new Enduron line of powders. To do this we carefully measured muzzle velocities of meticulously loaded ammo over a huge range of temperatures. This test was conducted by Patrick Middlebrook. Patrick is passionate about the art of precision rifles. He’s a great shooter who has competed in numerous local matches, and several national PRS matches. He is also a 5-star handloader. I’ve learned a ton from him! Patrick has become a good friend of mine (Cal, ...
