I'm building a 4 port brake for the 300 WSM I have in the works. I have the ports angled back @ 20°. My question is, which of these ways would be best? Should the entry into the first port be drilled through the same size for the 5/8 threads (9/16") or necked down like in the picture of the four port (.328)? Right now I have it built like the drawing. The other picture is one that I made for my Creedmoor with the muzzle even with the back wall.
Muzzle brake design question
- Thread starter Lead Slanger
- Start date
Have you ever shot off a bench next a bench where the person has a brake similar in design to yours ie ports angled to the rear. You might find you are not real popular with the adjacent shooters.
Just a heads up, I have seem things blown off benches by the reward blast of gas from the your style of brake.
I'm not suggesting you not make the brake, just want you to let persons next to you the range be aware of the blast.

No. What would be the advantage there? I've already threaded it 5/8-24.
I don't shoot in a lot of public range settings. When I do, I go with a retired friend of mine and we go during the week when it's just us out there. When I'm not shooting with him, I'm shooting on my home range on 40 acres of timber.

I ended up opening the rear of the first port out to 9/16". Not because I though that's what was best.... Because I was off on my math a little. Haha. When I cut the rear port, I barely cut into the opening I had for the threads (which was a little long). It turned out okay. As far as the port work.
I still have a little machining left on it. It's definitely cheaper just to buy one, but I just like to be able to say that I made it.

Well, here it is. Edit: The rear will be cut to match the barrel once I get one.

Has anyone tried orienting the vents vertically? 12 and 6 o’clock?

I agree with the idea that Steve suggest will occur, but...
Public ranges will always be a collective point of problems while shooting. I don't know of any benchrest shooters who use the everyday shooting range to practice. Too many drawbacks.
I do have to use a public range for some tests so I have built a 'blast shield' which mounts to the bench between my brake and my fellow shooters. I also use a brass catcher to control errant ejected brass.
For the most part though, I shoot out on the desert where others don't tread and skip all the fuss. Big backstop and much longer yardage. Quiet, peaceful, starlit nights. Just have to watch for the coyotes coming in to investigate the grill...

Just something to read.
For Barrel End Threading — Bigger Diameter is Better « Daily Bulletin
Our friend Robert Whitley of ARX Enterprises LLC has learned, through careful measurement and testing, that some barrels threaded 5/8 x 24 TPI at the muzzle may not deliver optimal accuracy. The reason is that the end of the barrel can bell out slightly, like a trombone, because too much steel...
Interesting. That'll be something to study and think on. If I decide to do that, it's not like I can't rethread the brake. Thanks.Just something to read.

You might want to look at this test.

Apparently there is actual science to it. Who knew?

I've read it before. It's interesting. My question wasn't about the port shape or design, but rather the size of the hole entering the first port. One miscalculation on my part answered my question for me. Large opening it is. Lol

KISS, I like their sled. I've made many different versions of brakes, truth is they all help and are louder than hell.

Yeah, I assumed you had it pretty well figured out. My post was more for someone who happened along later and might find it useful. Although the spelling did make me wonder a bit.
Break?Now if someone would just build a muzzle brake/supressor/tuner combo......?
