A Data-Driven Approach To Precision Rifles, Optics & Gear

Applied Ballistics Mobile Lab – The Future Is Here!

Applied Ballistics Mobile Lab

Well, when I started writing that last article on personalized drag models being the final frontier of predictive ballistics, I honestly believed I was going out on a limb and trying to predict something that might be years away. It turns out it was only months away! Welcome to the future! 😉 One of the biggest benefits I get as the author of PRB is getting to meet industry experts and have interesting conversations with the leading minds in various fields related to long range shooting. I absolutely love those conversations, and value them more than any payment I could ...

Personalized Drag Models: The Final Frontier in Ballistics?

Personalized Drag Models Bullet BC Long Range

I am super-excited about this article! I’ve actually been working on it for a couple of months, and I believe it represents some of the most interesting research I’ve come across in a while. Over the past several years, companies have started using Doppler radars to gain a much deeper understanding into the flight of a bullet. One ballistician told me recently that we’ve learned more in the last 5 years than the previous 75 years combined! In the last article, we looked G1 BC vs. G7 BC vs. Bullet-Specific Drag Models, including which of those the top-ranked precision rifle ...

G1 BC vs G7 BC vs Bullet-Specific Drag Models

G1 vs G7

“In the past 4-5 years we’ve made quantum leaps when it comes to predicting bullet trajectories.” –Dave Emary, Ballistician Ever wonder why you center punch targets at some distances, but your dope is a couple clicks off at other distances? Maybe your shots are dead on at 600 yards but off at 1000 yards, or vice versa. In those scenarios we often blame the rifle, scope, ammo, or ourselves, but is our firing solution as accurate as it should be? This article gives practical insight into some important nuances of predicting bullet trajectory, and shows what drag models the top ...

Ballistic App – What The Pros Use

Ballistic App

Ever wondered what ballistic app the best shooters use? Here are the answers! This article covers the ballistic apps the top precision rifle shooters are running to calculate their firing solutions for first-round hits at long range. The data is based on a recent survey I conducted of the top-ranked shooters across the country in both the Precision Rifle Series (PRS) and National Rifle League (NRL). (Learn more about the PRS & NRL). This is a very unique data set, because it includes a wide sample size (170+ shooters) who also represent the leading experts in the field. (View all ...

Best Rangefinder – What The Pros Use

Best Rangefinder

This article covers the rangefinders the top precision rifle shooters in the country carry in long-range competitions. This is the first year I’ve asked about rangefinders, so it was exciting to see which brands these experts trust to give them an accurate target distances. The data is based on a recent survey I conducted of the top-ranked shooters across the country in both the Precision Rifle Series (PRS) and National Rifle League (NRL).

Pocket Rangefinder Field Test Showdown

Pocket Rangefinder Review

Over the past few months, I’ve been testing several high-end pocket laser rangefinders, like the new Vectronix Terrapin X and Leica Rangemaster CRF 2800.COM, alongside other popular, top-of-the-line models in the $1,000+ price range. I used all of them extensively, and took them out to the field to test their ranging performance side-by-side. This post summarizes those results and other noteworthy points about features on each one. An accurate rangefinder is one of the most critical pieces of gear for long-range shooting. A few years ago, I wrote a post that quantifies how much range uncertainty can impact hit probability. ...
