Vote For The Best 6.5 Creedmoor Match Ammo

Best 6.5 Creedmoor Ammo Review

I recently tested every popular type of 6.5 Creedmoor ammo, and carefully collected data on the performance of each one. I thought it’d be fun before any of the results are published to poll my readers to see which type of ammo you expect to end up on top. What do you think will perform the best when it comes to hit probability at long-range (e.g. 600 to 1200 yards)? Cast your vote and see what other readers think will end up on top!

Bullet Jump Research: Executive Summary & Load Development Tips

This is the last post in a series of articles focused on bullet jump research that has been conducted more than two years by Mark Gordon of Short Action Customs (Who is Mark Gordon?). In this post, I’ll provide an executive summary of what we covered and provide a few tips for how to apply this new knowledge in our load development. The first article provided a comprehensive overview of what 10+ of the most respected books and reloading manuals had to see about bullet jump and laid the foundation of what bullet jump is, along with other concepts like ...

Mark’s 18-Shot Bullet Jump Challenge!

Mark's 18 Shot Bullet Jump Challenge

Are you one of those guys who has been reading this series of posts on bullet jump, and thinking to yourself, “Well, my 0.020” bullet jump sure seems to be working fine. Doubt this would be any improvement over what I’ve already got!” This is the post for you! As Mark started sharing some of his bullet jump findings with a few shooters, he met some skepticism – even from sponsored shooters on his Short Action Customs team. Here is how Mark tells one of those stories:  “After we’d already done most of this bullet research, we had Solomon from ...

Bullet Jump: Is Less Always Better?

Bullet Jump Load Development

This landmark article shares new, primary research that Mark Gordon from Short Action Customs has compiled over the past 2 years. He tested a wide range of bullet jumps in several rifle/load configurations, and this post shares the analysis of that data. Mark used a similar approach to the Audette Ladder Test and OCW method, but the goal was to not find the most forgiving powder charge weight, but the most forgiving bullet jump. He wasn’t looking for the specific bullet jump that grouped the best, but the largest window of bullet jumps that provided a similar point of impact. That means the rifle would be more consistent from the start of the match to the end of it or could shoot a particular kind of match-grade factory ammo really well for a longer period of time. Mark’s findings may seem counter to conventional wisdom when it comes to bullet jump, but a few national-level precision rifle competitors also support the idea, which I highlight in this post as well.

How Fast Does A Barrel Erode?

how fast does a barrel wear

This article focuses on how quickly the lands of a rifle barrel usually erode, especially for mid-sized cartridges that are popular in precision rifle matches. It also explains how many shooters try to manage their seating depth and bullet jump over the life of the barrel. These are topics don't seem to get much attention and are rarely discussed in any comprehensive format, so hopefully it provides some useful information and tips. The article also poses some questions that might make us rethink priorities when it comes to managing bullet jump, at least when applying the concepts to some specific shooting disciplines where you might fire 100-200 rounds over the course of a weekend.

Bullet Jump & Seating Depth: Best Practices & Conventional Wisdom

Bullet Jump and Seating Depth Reloading Best Practices

With so many events canceled and stores closed, what a great time to do some reloading! Over the past several weeks, I have been working on a series of posts that I'm very excited to finally share with you guys! This article provides a comprehensive overview of what most professionally published books and reloading manuals suggest about bullet jump and seating depth when it comes to precision rifles. I have a big stack of books on the subject, and I tried to combine the most relevant info from each of them when it comes to fine-tuning the seating depth of your ammo.

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. ...

Barrel Field Test Featured In Modern Advancements Volume 2

Barrel Test in Modern Advancements In Long Range Shooting

Lots of people have asked what I’ve been working on, and I’m excited to finally be able to tell you guys about a huge project I’ve invested a ton of time in over the past several months. Last year, Bryan Litz and team over at Applied Ballistics ask if I’d be interested in contributing to Volume 2 of their Modern Advancements in Long Range Shooting series. I have immense respect for the work those guys have done and the huge impact they’ve had on me and the rest of the shooting community, so I was honored to even be asked. ...

Muzzle Brake: Summary of Field Test Results

Muzzle Brakes

This post summarizes the eye-opening results for the massive muzzle brake field test I’ve worked on the past few months. It included several objective tests to quantify the performance of 20+ muzzle brakes designed for precision rifles in 6mm through 30 caliber. My goal with this project was to equip fellow long-range shooters with as much hard data as I could reasonably gather, so they could make an informed buying decision for their application. I’ve already published ridiculously exhaustive details of each test, but I’ll try to sum it up in this post. This test focused on muzzle brakes designed ...
