Fast shooter go to the link. Go to bottom of his page, watch his videos? If you don't take something from that I wouldn't see how you could tell right threads from left??
Sorry Bubb didn't notice the videos. I looked for a test link on the side and scrolled down a ways but not to the bottom obviously. I am new so my post was delayed(didn't see your watch video post)
I would suggest they add a link on the side to get a little more action from people w ADD.
I did watch some of them now. No doubt a good comparative test. No doubt very effective brakes.
I'm sure they are high quality and all that but I would think you can get stuff just as good here except for maybe the on/off model.
I counted 50 muzzlebrakes on the Brownells website. I'm sure some of them are model specific but:
Muzzle Brakes | Barrel Parts at Brownells
And that's just Brownells.....
As far as reduction goes it will depend on how much muzzle blast you're willing to deal with and how big a brake you want to deal with. As Jeff was thinking you might not be able to get past a certain point of reduction.
As for the Holland (quick discharge?)...that's just a copy w a few top holes of the ol Miculek comp that we used to get for $30. The 3 port brake they(D.F.) show is almost exactly the same as the ol Miculek comp.
One of the most effective brakes I purchased in the mid 90's called a "Master Blaster". It has a fish gill design and punishes anyone around the shooter but damn does it work.
More ports is usually better but in the same length more ports mean thinner wall which means less life-not a problem in a hunting rifle but something that sees a lot of ammo will erode quicker.
As a side note their testing fixture does not tell them how much muzzle movement and in what direction. That does not matter for hunting I guess but for Tact/Comp you want something that stays on target.
I applaud D.F. for their efforts and I too wish that there was more testing done and posted here in the US.
