A more quiet suppressor on a 50 BMG rifle ?

We don't quote what is "hearing safe."

Our current dB #'s for the Ultra 50, on a 27" rifle, metering at shooter's ear, is about 139 dB if the supersonic crack is omitted (ie actual muzzle suppression). The peak from the SS crack at shooter's ear is between 140-141. This is with the muzzle brake on the end of the can. With the flat cap instead of the brake, it's at least 7 dB quieter @ SE
 
Would the CGS Keres or Thunder beast be hearing safe?

"Hearing safe" isn't really a thing unless you're talking bolt action subsonic suppressed with long/quiet silencers.

What rifle are you suppressing? Bolt action or semi auto? Barrel length?

Hearing damage is dose dependent. What is the planned firing schedule? Where are you firing it? Are you in the free open feild? Are you going to be inside something, under a shade cover, next to walls, etc? Is the muzzle going to be less than a foot off the ground or 4-5' up on a tripod. Just be careful with people telling you or thinking things are hearing safe.

All of this matters in terms of hearing damage potential. The more reflective surfaces and the closer you are to them the more hearing damage potential there is.

If I had to guess by just looking at that tbac can with that brake I'd say the Keres is probably quieter but the tbac will probably have quite a bit less recoil because of that brake. So there's a give and take between the brake cap vs solid.

Edit saw Zak mention they have a flat cap. When I said Keres is probably quieter it was in reference to the tbac with the brake. I'm not making assumptions on solid cap vs solid cap.

We have some meter data that showed we were quieter even with the brake, but we need to re-do it due to some ambient problems. Nothing we've metered was even close to the long config with the flat cap (no brake), but nobody wants to shoot a 50 without a brake on the end of the can
 
The CGS Keres is an option, as is that TBAC above. Id lean that way anyways. I dont think id consider a QD 50 can, personally.

KGM makes a 50 can, but I’ve heard zero about it.
The KGM is pretty good for sound but recoil mitigation isn't amazing. I'm not sure anything really is. By all accounts the Thunder Beast looks amazing but is a monster.

That's nice dang. Buddy has the Barrett MRAD system and the suppressor from Barrett.....his dang 338NM and 300NM/6.5 no matter what are the quietest on the entire range and there are a ton of suppressed rifles at our range. Amazing. Cool to see a 50 tamed too.

Was not impressed haha with either the sound suppression or recoil mitigation....

Better off with a brake than that kgm can lol
 
Zac. Is the Tbac 50 working on a Barrett M107?

I don’t see the point in suppressing a a 50 BMG. The extreme cost, length and weight - juice just ain’t worth the squeeze. And with cans other than TBAC you’re going to have a notable increase in recoil which will affect your shooting and I don’t care what you read with guys saying “it’s fine”. It’s probably fine for IPSC inside of 1000 yards. It will rattle your cage and there are few superhuman shooters out there who are not affected by it unless they’re plinking big targets, thumping their chest, and trying to prove how manly they are.

I added 11” to my DT barrel (40” total) and get another ~150 FPS. Cost $100 extra for the blank, and the foot of length

I can see specific scenarios where you may want it. I’d rather spend my $6000 elsewhere and get free velocity - and muzzle chaos farther in front of me that way

Next time I may go to 45” which is the barrel length John Browning designed the cartridge for.

Finally, if you’re planning on suppressing the factory DT barrel, look carefully at the threads. They’re using metric and it can be difficult to find a compatible muzzle device.

YMMV
