Muzzle Brakes: Recoil Results for 6mm & 6.5mm

6mm 6.5mm Muzzle Brake Rifle Recoil Results

This post summarizes the results for the recoil tests ran on 20+ muzzle brakes using 6mm and 6.5mm test rifles. To see the full line-up of muzzle brakes tested, check out this post. The recoil data was collected using high-speed, high-resolution force sensors. For more info on the test equipment and how the data was gathered, please see the previous post. How to Read the Results As we discussed in the last post, when someone claims a product “reduces recoil by 50%” … it usually isn’t clear what they’re talking about. Unfortunately, there is no industry standard for measuring recoil, ...

Muzzle Brakes: Recoil Primer, Test Equipment & Rifles

Rifle Recoil Test Setup

This post provides a primer on recoil, and then explains how I measured recoil, including the approach and specific equipment used. It also reviews the rifles and cartridges tested. What do we mean by recoil? I’ve read a thick stack of articles and white papers on this subject, and suffice to say we can get pretty deep in the weeds if we weren’t careful. But, I’m going to try to keep it simple and on point. For our purpose, recoil is the rearward kick we feel when we fire a rifle. I’m less interested in the esoteric mathematics-based models (although ...

Muzzle Brakes: Field Test Overview & Line-Up

Muzzle Brakes

This is the first post in a series that will cover the results from an epic muzzle brake field test. This represents an unprecedented, data-driven approach to evaluating the best precision rifle muzzle brakes on the market. Hundreds of hours have gone into this research, and the tests I conducted are built on advice and feedback from some of the most respected experts in the industry. This included leading manufacturers, top shooters, gunsmiths, mechanical engineers, university faculty, and defense contractors who have done similar work for the military. Thanks to all the guys that helped me with this! I tested ...

New Berger 6.5mm Bullet for PRS Shooters

Berger 6.5mm 130gr Hybrid Bullet

Berger recently released a new 6.5mm 130gr Hybrid bullet. Bryan Litz, Chief Ballistician at Berger Bullets, told me “This bullet was optimized for magazine length ammo based on the popularity of the 6.5mm cartridges in PRS competition.” 6.5mm cartridges like the 6.5 Creedmoor, 6.5×47 Lapua, and 260 Remington are very popular in those types of competitions (see the full list of the most popular cartridges). In PRS events, multiple targets are engaged at each stage, often within a ridiculously short amount of time … so magazine feeding is a must. Bryan and the team at Berger created a bullet optimized for ...

7 Ways the New ARC Rifle Action Blends the Best of Old & New

Ted Karagias of American Rifle Company (ARC) wowed us last year, with his fresh and innovative complete rifle system and an action, earning the title of Most Innovative Product of SHOT Show 2014. Now his Mausingfield Action has officially made it into production, and is available to the public. It received a lot of attention at SHOT Show 2015. A few weeks ago, Ted sent me action serial #00001 to test, and I used it to fire hundreds of rounds of Hornady 6.5 Creedmoor Match Ammo. Here is a quick video that highlights some of the features of ARC’s Mausingfield Action, and ...

Tactical Scopes: Field Test Results Summary & Overall Scores

This is the executive summary and overall scores from an epic scope field test focused on long-range, tactical rifle scopes in the $1,500+ price range. This represents an unprecedented, data-driven approach to evaluating the best scopes money can buy. Over 400 hours have gone into this research, and the line-up and tests are built on advice from some of the most respected experts in the industry. 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 see what they’re paying for. I’ve published ridiculously exhaustive details, ...

Tactical Scopes: Advanced Features Summary

Sorry, guys! I forgot to calculate the scores and post the summary for the advanced features section (e.g. reticles, zero stop, etc). I didn’t notice it until I went to calculate the overall scores! So I’ve gone back and figured that out, which is what this post is about. Don’t worry … the next post published will be the final overall results, I promise. Rifle scope innovation seems to have found a new gear lately, and that has led to a mountain of new features that simply weren’t available a few years ago. While many of these new features are ...

Tactical Scopes: Mechanical Performance Summary

A great scope is more than just sharp glass. I surveyed 700+ shooters, and mechanical performance was rated as the most important feature of a scope. In fact, mechanical performance received 30% more votes than optical performance. A scope that doesn’t track, or doesn’t have repeatable adjustments seems to be viewed as the biggest flaw a scope could have. Mechanical performance is a critically important topic, but has been largely neglected in the shooting press. Here is what Dennis Sammut, Founder/President of Horus Vision, has to say on the subject: “Yearly, a virtual mountain of written information is spewed forth ...

Tactical Scopes: Mechanical Performance Part 2

The previous post contained the details of the mechanical calibration test, which I think was one of the most enlightening tests of this entire field test. This post reviews several other tests I ran related to mechanical performance, including: Scope repeatability and whether it could reliably return to zero Reticle cant Reticle calibration Max internal adjustment range (i.e. elevation travel) Elevation travel per revolution Windage adjustment range Magnum recoil box tests Lots to cover, so lets dive into the results. Repeatability & Returning To Zero The setup of this test was identical to the click calibration test I covered in Part 1. Instead of ...

Tactical Scopes: Mechanical Performance Part 1

This is one of the last posts covering the detailed data collected over the past 4 months for an epic scope field test focused on long-range, tactical rifle scopes in the $1,500+ price range. This represents an unprecedented, data-driven approach to evaluating the best tactical rifle scopes money can buy. Hundreds of hours have gone into this research, and both the scope line-up and the tests I conducted are built on advice and feedback from some of the most respected experts in the industry. My goal with this project was to equip fellow long-range shooters with as much hard data ...
