This HOWA 1500 was an example of another rifle setup that has proven to be sensitive to things like load variations, and even having a Magnetospeed chronograph attached. Test Scenario 3: HOWA 1500 Custom 6mm Creedmoor with Handloads With this rifle setup, it may be worthwhile to try different bullets and loads *with* the EC Tuner Brake to see if things can be improved even more (story in progress). The ~0.6 MOA groups at setting “4” and “10” were good. These results were a bit less conclusive, but you can see here how the tuner setting did indeed have a *large* effect on group size. The same testing methods were applied for this scenario. We were seeing some pretty heavy harmonics and shot dispersion with Hornady 147 grain ELD-M factory ammunition using this setup, so we thought we would see what the EC Tuner brake could do to help out. The second test used a Bergara HMR Wilderness rifle in 6.5 PRC, put into an XLR Element 4.0 Magnesium chassis with weights and rear bag rider. Test Scenario 2: 6.5 PRC with Factory Ammunition This was a great result with a very respectable 0.37″ group (for factory ammunition). Here were the groups for this round of testing: We stopped each test when we saw the groups contract and then expand again, or when we ran out of ammunition! This is first-round testing, with lots more follow-ups. The mass can be turned out multiple times, but we never needed more than a bit over 1 turn to get interesting (good) results.Īnd here was our test process (for all shooting in this article). There are also minor graduation marks between each major graduation, yielding 20 total “tick marks” for each turn of the tuner mass. The EC Tuner Brake has 10 major graduations on it’s scale per revolution. Length: 3.3″ Test Scenario 1: 6.5 Creedmoor, Factory AmmunitionĪbove you can see Travis Fox performing the test shooting with a custom 6.5 Creedmoor rifle and Federal Premium 130 grain factory ammunition. They are made of 303 Stainless Steel for maximum corrosion resistance. The tuner allows you to manipulate the harmonics on your barrel to match your load for best accuracy possible. On the other end of the muzzle brake, it includes tool less design tuner. It also has a self timing nut so that you can time it correctly on your barrel. This 4 port muzzle brake has an expansion chamber for maximum recoil reduction.
