6.5 Creedmoor Ammo Test Part 4: Live-Fire Muzzle Velocity Details

6.5 Creedmoor Ammo Muzzle Velocity

This is the second article in this series covering the muzzle velocity data I collected. The last article covered how this data was collected, along with a summary and head-to-head comparison of all the 19 different types of match-grade factory 6.5 Creedmoor ammo that was included in this research. If you haven’t read that article yet, I’d suggest starting by reading it – but here is a quick summary: I bought two boxes of 19 types of 6.5 Creedmoor ammo that were marketed as “match” or “target” grade. Each box was purchased 6 months apart from different distributors to get ...

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 ...

6.5 Creedmoor Ammo Test Part 2: Physical Round-To-Round Consistency

6.5 Creedmoor Ammo Consistency

I’m so excited to start sharing the data I collected in a massive field test I conducted on 19 different types of 6.5 Creedmoor match-grade factory ammo. With the price of this kind of 6.5 Creedmoor “match-grade” factory ammo hovering around $3/round right now, it seems like this series might be especially relevant! That’s too expensive for most people to experiment with several brands and types of ammo, so hopefully, this research will help guys narrow down their search to a couple of the best-performing brands and types to try in their rifles. I know there are a ton of ...

6.5 Creedmoor Ammo Test Part 1: Intro & Reader Poll

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 ...

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.

300 Norma Mag Custom ELR Rifle

300 Norma 338 Lapua Custom ELR Rifle

I’m sharing a series of posts on ELR shooting, but I didn’t want to jump from the long-range rifles in mid-size 6mm and 6.5mm cartridges that I normally talk about straight into the extreme, super-high-performance 375+ caliber rifles used to engage targets at 2+ miles. Instead of just presenting the extremes, I thought it’d be helpful to first share a rifle setup that is somewhere in between. Then in later posts I’ll get into the more specialized setups used to push the boundaries of what is possible with shoulder-fired rifles. In this post, I’ll share the details of a rifle ...

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, ...

Reloading Like A Pro – Tips From Top Precision Rifle Shooters

Reloading Tips From The Top Precision Rifle Shooters

I’ve surveyed the top 100 shooters in the Precision Rifle Series (PRS) for the past 4 years, and published what gear they’re running in my annual “What The Pros Use” series of posts. This year, I also asked a few questions about their ammo loading practices and how much they practice. When handloading there are a thousand operations and details you can spend time trying to perfect. It’s easy to get caught up trying to do them all, or spending a ton of time focusing intently on a couple of aspects and completely miss other important steps. But I was ...
