![]() 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. To see the full line-up of muzzle brakes tested, check out this post. This post summarizes the results for the recoil tests ran on 20+ muzzle brakes using 6mm and 6.5mm test rifles.
