surface area the gas has to work against), angle of the baffles, distance between the baffles, etc. The brake designs vary by number of baffles, size of the baffles (i.e. That is interesting, considering there are many different designs represented in that cluster. Both of those brakes had outstanding performance in terms of recoil reduction.īeyond that, there was a big group of muzzle brakes in 26-36% range of recoil reduction. There were two muzzle brakes that separated themselves from the rest of the group: the brand new Alamo Four Star Cowl Induction Muzzle Brake, and the very popular American Precision Arms (APA) Little B*. Without further ado, here is the data for the recoil reduction on the 6mm rifle for each muzzle brake:Īny surprises? I have to guess there might be a few. It represented the heaviest rifle in our test, although that weight is not uncommon for a precision rifle. That weight includes the scope and mount shown in the photo. My 6XC rifle weighed in at portly 16.2 pounds with a bare muzzle, and no bipod or magazine.

All 3 cartridges are very popular among the top shooters in the Precision Rifle Series ( see the data). That load is also roughly representative of the popular 6mm Creedmoor or 6×47 Lapua cartridges. I used my personal handloads for testing the 6XC, which launch a Berger 105gr Hybrid at 3,000 fps. The rifle used for this was chambered for the 6XC ( view rifle details). We’ll start with the smallest caliber tested, the 6mm. To learn more about those measurements and hear the cases experts make for both sides, please read the previous post.
Average % Reduction – This is just the combined average of the previous two measures (evenly weighted). It’s essentially how tall the highest point on the curve is. % Reduction in Peak Force – This is the reduction in the highest instantaneous peak force through the entire recoil event. It isn’t just the peak force, but the entire “area under the curve” when you graph force over time. It represents the total “size” of the force that I described in the last post. % Reduction in Overall Momentum – This is the reduction in overall impulse or total momentum of the rifle at the end of the recoil. For each muzzle brake, I will show 3 pieces of information: Here is an example of the results I recorded for one of the muzzle brakes:Īs I publish these results, I plan to show how much each muzzle brake reduces recoil compared to a bare muzzle. You can watch a video of me running through this for one of the muzzle brakes in the previous post. So I backed that down to only be 3 shots per muzzle brake. I started out firing 5 shots per muzzle brake, but as I refined the system and setup, my data became so consistent and repeatable that 5 shots seemed like I was just wasting a lot of good match-grade ammo without adding any value. The results are based on the average of multiple shots fired with each muzzle brake. Honestly, I’m not here to try to convince anyone one way or the other, but simply present the data. As we learned in the last post, it seems like it may be short-sighted if you ignore either of them. Some experts lean more towards that being related to the total impulse or momentum, and others think it is more linked to the peak force. The big question comes down to what measurement most closely correlates to perceived recoil from the shooter’s perspective. Unfortunately, there is no industry standard for measuring recoil, which means manufacturers often publish whatever makes them look better. For more info on the test equipment and how the data was gathered, please see the previous post.Īs 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. The recoil data was collected using high-speed, high-resolution force sensors.
