Muzzle Brake Comparison Test by Precision Rifle Blog

Cal Zant Precison Rifle Blog AccurateShooter Muzzle Brake Test Noise Recoil Reduction Video

Another massive, data-driven field test has been completed by our friend, Cal Zant, over at PrecisionRifleBlog.com. The past few months, Cal has tested 20+ muzzle brakes designed for 6mm, 6.5mm, and .30-caliber precision rifles. Hundreds of hours have gone into this research, and it provides a lot of new insight and empirical data for several aspects of muzzle devices. Cal put a huge amount of labor/engineering into these tests and his findings deserve to be widely read.

PRB Muzzle Brake Test Methodology

Recoil Reduction
Cal created a system to directly measure the entire recoil force signature of each muzzle brake using high-speed sensors. Although the recoil cycle happens very quickly (around 1/100th of a second), his test equipment could record up to 1,000 force data points during a single recoil cycle! He fired over 1,000 rounds of match-grade ammo through four different rifles: 6XC, 6.5 Creedmoor, .308 Win, and the monster .300 Norma Magnum. He literally spent thousands of dollars on this part of the test, to ensure he got it right.

Cartridge Types Tested: 6XC, 6.5 Creedmoor, .308 Win, and .300 Norma Magnum

Ability To Stay On Target
David Tubb helped Cal develop this part of the test, because David believes this is the most important aspect of a muzzle brake. Using a laser and high-speed camera, Cal was able to objectively quantify how well each design helped you stay on target.

Noise Level
Muzzle brakes are loud, but some are louder than others … three to four times as loud. Cal enlisted the help of an expert from the suppressor industry to precisely measure how much louder each muzzle brake made a rifle. Each brake was tested in accordance with MIL-STD-1474D using calibrated military-approved equipment, and the noise level was also tested at the shooter’s position. This produced some interesting results.

Zant also includes high-res photos of each brake, and plans to publish other info about each model (including price, whether it requires gunsmithing, what calibers it is available in, etc.) to make it easy to compare them side-by-side.

Cal recently started publishing the results of these tests, and there is already a lot of interesting info. The data might surprise a few people and even dispel a few myths. Particularly interesting is Zant’s comparison of recoil reduction with a suppressor compared to muzzle brakes. How do you think the suppressor performed compared to the brakes? You may be surprised.

New Super-Short Mini Action Rifles from Howa

AccurateShooter Howa Mini Action .223 Remington Rem Varmint rifle short action

Howa now offers “Mini Action” rifles with actions that are nearly an inch shorter than typical “short actions”. With the Mini Action, the chamber and bolt are 12% shorter than regular short actions with shorter bolt throw for faster reloads. Weight is also reduced with a shorter bolt. The Howa Mini Action rifles come with ten-round, synthetic detachable box magazine and a reasonably light HACT 2-stage trigger. This makes for a nice, compact (and very shootable) varmint package. Nice enough, in fact, that we are looking seriously at the Mini-Action Howa as a donor for a .221 Fireball varmint gun project. We like the idea of a shorter action with a compact 10-round mag.

AccurateShooter Howa Mini Action .223 Remington Rem Varmint rifle short action

Howa Mini Action rifles chambered in .223 Rem are available now with 20″ lightweight, 22″ standard and 20″ heavy barrel options. Other chamberings, including the .204 Ruger, will be available soon. Synthetic stocks designed to fit this new Mini Action configuration are offered in black, OD green, and Kryptek Highlander camo colors.
