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.

Rifle Caliber – What The Pros Use

Rifle Caliber

Welcome to “What The Pros Use” 2018 Edition! I recently surveyed the top ranked shooters in both the Precision Rifle Series (PRS) and the National Rifle League (NRL) to learn what gear they’re running in long range rifle matches. These guys represent the best precision rifle shooters in the country, and over the next several posts I’ll be publishing the results. Learn more about the PRS & NRL. Most Popular Rifle Caliber I can remember a time when there was a battle between which caliber was most popular: 6mm or 6.5mm? That battle appears to be decisively won at this ...

Custom Twin 6mm Match Rifles

6mm Creedmoor Rifle

A couple of years ago, I wrote about a custom 6XC precision rifle I had built that I used in PRS-style matches. Since that time more precision rifle products have been released than the previous 10 years combined! So last year I started from scratch and built two twin match rifles. I’ve been running this rifle setup for a year now, making small tweaks along the way, and I love how I have it configured. While I don’t believe in any one rifle being the “best” for all shooters and applications, this setup seems completely ideal for my use. I’m ...

SHOT Show 2018: Nucleus Action from American Rifle Company

Nucleus Bolt Action from American Rifle Company ARC

Over the next few posts, I’ll share the top few precision rifle products that caught my attention at SHOT Show 2018. As always, it’s impossible to see everything at the show, but these are some of the items I noticed that I thought my readers might like to know about. The first product I’ll highlight is the Nucleus bolt action from American Rifle Company. ARC caught my attention at SHOT 2014 with their Mausingfield action (see full review). While most high-end actions are simply improved versions of the Remington 700, the Mausingfield was a refreshing design combining a couple of ...

Long-Range Calibers & Cartridges: What The Pros Use

Long Range Calibers and Cartridges

I recently surveyed the top 100+ shooters in the Precision Rifle Series (PRS), and this post reviews the calibers and cartridges those guys are running this year. For those of you who may not be familiar with the PRS, it’s an organization that tracks how top competitors place in major rifle matches across the country. PRS matches are tactical/practical long-range rifle matches shot in the field conditions. Typical ranges for steel targets are from 300 to 1200 yards, and they are engaged from prone and improvised positions, often under extreme time pressure. It is one of the fastest growing shooting ...
