Silenced .50BMG

[anodes]

So I finally got off my <chair> and scanned in some pics from the (not so) recent 2nd Cornville MG and Silencer shoot. The weather was great, the people were better, the guns were FANTASTIC. I have uploaded a couple pics from the day showing a silenced .50. Sorry about the size, scanned in from a disposable cam. Attention to detail will show that the silenced BMG is actally pedistal mount and claped to a rather heavy table, compensating for a lack of effective muzzle break. Further attention will discern a "cute" dual bbl 10/22 Gattlin' Gun that is loved by some... :madeuce: Any others are exrta credit!

Devin takes a whirl. Love that muzzle blast!

Devin shoots a BMG for the second time. No, these last two aren't silenced.

note how I didn't f/u the img rotation!!:)

Where the heck is Cornville? LOL

That suppressed .50 looks cool but I bet the table would be a bitch to CCW :)

cheers

[anodes]

lol, Cornville is in between Beaver Hollow and Page Springs... if that helps!;)

I put these in (the wrong forum) just because I liked the flag in the one and Chris shooting a F/A Glock for the first time. I brought three young guys w/soas to "lite a pro-gun fire" under thier enthusiasim... It worked!!!!!!;) :dgrin: :uzi:

ETA, love that Gattlin' Gun!!!!!!!!!!;)

[RIKA]

Looks like fun. Can you compare the sound the suppressed .50 makes to anything that we would recognize soundwise? Like maybe, "it sounds like a whip cracking" or anything like that.

I love your photos, especially the one with the flag. Thanks!

R, It is LOUD. Kinda like a pallet of water mellons being dropped off a 20 story building. You've heard that right? lol OTOH, there was a FA silenced Uzi that actually made a sucking, whistleing noise. Wierd. Fun, but I didn't get a whirl w/the Glock or Uzi, I was more concerned about given any "turn" I had to the guys.

Was foolin' w/the first pics size for more detail and could not find the edit button in my first post? Pardon the dup.

Dang that is a huge suppressor...

I have a McMillan Boomer .50 BMG with an AWC Turbodyne suppressor that was matched to the barrel. The sound is about the same as an unsuppressed .22lr out of a marlin model 60 rifle. Recoil reduction... well, all I can say is that it's IMPRESSIVE.

The Turbodyne is 2 inches by 12 inches long. It weighs about 2.5 pounds and is awesome. My main complaint is having to pull the muzzle brake to put the can on the gun... but alas, it's worth it.

how much baffle erosion is to be expected on those things? i.e. what is the anticipated life for the first couple of baffles?

[Hard Rock]

Well, on the current Turbodyne I own, I have about 5000 rounds through it. The previous one outlasted 4 barrels and a tumble out of the back of a pickup truck to be sold with the Mcmillan M88 I had it mounted on. I didn't notice any degradation of the baffles on the first and I'm looking at the one I own now and there is no visible wear at all.

Mike

[RIKA]

Mike, what material do they make those baffles out of. Guess what I'm asking is, it it a matter of material or of design?

RIKA

[Hard Rock]

Both... AWC uses stainless steel only in the Turbodyne. The baffle design is a modified K baffle that really does a good job on working with the pressure. One thing to take into account is that the wear on a suppressor comes from the pressure of the gas not the volume. The CUP on the .50 BMG is about the same as on the .308... about 55,000 CUP. In the scheme of things, that isn't a destructive pressure considering the size of the cartridge. Also, if you run older corrosive ammo through the suppressor, it'll resist damage better than carbon steel.

After messing around with suppressors for so long, I've come to the conclusion that the extra weight of stainless steel is worth every oz. when it comes to service life and performance. You'll also find that the extra weight helps with the barrel vibration during firing giving you much better consistancy and better long range accuracy.

as short as the barrel has to be in that photo, you couldn't get more than a small fraction of the power normally available with the full power .50.

[Rich Z]

Actually I have heard that those short barrel .50BMG rifles have a substantial hit in projectile velocity. Plus I would imagine that the muzzle flash is quite astounding.

[andy]

no kidding? The issue barrel, the one the rd was developed for, was 38" long. Yeah, I'd say that an 18" barrel would have a LOT less velocity than the 2800 fps that is achieved by the standard load in the 38" barrel.

[Hard Rock]

Barrels longer than 35" are best suited for the same powder that the 20mm Vulcan round uses... forgive me for not remembering the name... but it's much slower than standard IMR powder used by the military. That powder is geared for the M2HB and M107 rifle. I believe the optimum combination of accuracy and velocity is 22-26 inch barrels.

Mike

[andy]

u "believe" WRONG, dumbass, in the case of the .50 bmg.

[Hard Rock]

Really? How many .50's have you fired in the last 10 years? I've fired all five of mine enough to where I've had to replace the barrels in each twice at a minimum.

I have a McMillan Boomer .50 with a 26 inch barrel that provides me with 2700+/- fps with IMR 5010. However, with the WC872 20mm cannon powder, I loose a LOT of velocity in that gun. I only get 2300 fps.

Now, put that round in my Boomer .50 repeater with the 36 inch barrel and I'm running a 750 grain AMAX around 2800 fps. But, with the IMR 5010 in this gun, I lose velocity and am getting 2500 fps.

But according to you, who has no experience in firing .50's, and no knowledge on the .50's at all, you say I'm wrong... go figure.

Mike

[blueboy]

I know you're fos about what you CLAIMED, liar, which was 22-26" barrels do ok. Besides the barrel in the photo is MUCH shorter than 22", or the can couldn't possibly handle full charge .50 bmg ammo. You're nothing more than a liar, Hard Rock. You lied about me sending you threatening emails, you lied about the baffle hole size in 223 cans, you lied about your 308 loads, you lied about your 338 barrel's longevity, you're just a ****ing liar, all the way around, and all the time.

[Coyote]

Uh oh! Melvins on the warpath! About nothing, again!

Just wait Hard Rock, in 2-3 years, long after we've all forgotten about this particular childish outburst (there have been so many) he'll bring it all up again!

What fun. :rolleyes:

[Hard Rock]

I'm sure... his understanding of physics is amusing though...

Note: "Besides the barrel in the photo is MUCH shorter than 22", or the can couldn't possibly handle full charge .50 bmg ammo."

With a shorter barrel, more pressure and gas expansion has to be countered by the suppressor. Basically, his understanding of how a suppressor works is exactly opposite of reality. The longer the barrel, the easier it is on the suppressor. Oh, and if the suppressor is properly made, it doesn't matter what barrel length the gun is, the suppressor will handle full power loads. I know both of mine will.

Basically Gunkid, The longer barrel allows for complete powder burn and the pressure spike is on the waning side before the bullet gets to the muzzle. If you shorten the barrel, you get more pressure and the can has to deal with more burning powder and higher temperature gasses.

Mike

[hearty]

so what? The POINT is, the pictured gun has no room for much barrel inside of that can-telescoped around it. You KEEP trying to duck the issue, but I won't let you.

hard-rock! GREAT THREAD.,,, I'm a 'little-fish' in the .50's[i really just smack/crack rocks with mine],,,here's a link to a photo

[minus the tripod,of course]

[RIKA]

Oh wow. Thats some rock smacker, Brass.

RIKA

[Hard Rock]

That gun is an integrally suppressed design. If that is the same gun I'm thinking of, the barrel is 16.5 inches long, is ported and is designed to keep the round subsonic while making kill shots at 300 yards.

That is a special application piece. My rifles fill a much broader role. Like making 2500 yard shots.

Mike

[andy]

just like I thought, It's NOT capable of suppressing full charge 50 BMG ammo. So you might as well say its 45-70, cause 750 grs at 1050 fps is just 1850 ft lbs, not the 10,000+b ft lbs of the full charge load. HUGE difference.

[Hard Rock]

Wrong, it uses full power .50 BMG loads... The same rounds that would leave my guns at over 2600 fps. What it does is it ports the gasses to keep the rounds subsonic. Personally, I think it's a waste since the effectiveness of the .50 is cut way down but the owner likes the thought of putting a 750 grain bullet into a target at 300 yards with almost no sound at all.

Learn about suppressors Gunkid... your ignorance is blinding.

[dardani]

hello folks ,hello rock. they say turbodyne is very loud 50 bmg can, in fact it was one of the best cans ,tested really great at shot show 2006, you can take a look at silencertests.com, so people do not belive every bull**** they say around without proving or hearing by yourself.

[Hard Rock]

Hey Dardani! How you been bro?

I've heard Turbodynes that were VERY loud... simply because the can wasn't designed for the platform it was used on. The design of the Turbodyne varies with the weapons system and barrel length. For instance, I wouldn't adapt one that was made to work on a Barrett to operate on a McMillan. It won't work well.

That is why when they recommend you send the gun to them that the can is going to be installed on, you get several things done... first the threads are verified... meaning that they are in line properly with the barrel. Secondly, the can is then designed around your rifle for maximum effectiveness.

This is one reason that the military has been slow to adapt a suppressor for the .50 BMG on a large scale.
