First let me say I know the fishbones are coming because this is yet another invention in an unpopular field: weaponry
Before I throw my idea out there let me first start with a few facts about firearms the readers may or may not be aware of:
1)Adding a silencer or suppressor will can
reduce the noise made by a firearm but can do nothing to silence the miniature sonic boom that causes an audible "crack" that makes the suppressor pointless unless one is using subsonic ammunition
2)Prime candidates for suppressors are usually pistols or submachineguns(which happen to use pistol ammunition) because little stopping power is lost by slowing down a pistol round to a subsonic speed
3)Rifles (both assault rifles and sniper rifles) depend on a small round going very fast (well above sonic speeds)
4)Once rifle rounds are slowed down to subsonic they lose much of their beneficial characteristics: Superior range, penetration and accuracy
That being said, this idea involves modelling a new round after (what I think) is the ideal ammunition for silencing, the .45 calibre pistol round. It is known for it's superior stopping power and "nail-driving" accuracy compared to other pistols. Another terrific characteristic is that it is naturally subsonic so no reduction in velocity is needed.
Now the jist of the idea is to make a scaled up version of this round along with a rifle specifically made for it, that has an integrated silencer similar to the MP5SD. This weapon would (hopefully) offer a marksman a long range weapon with devasting energy transference without the worries of alerting the opposition.

true I suppose..but wouldn't the inertia of the heavier round have a positive effect on range? My physics is a little fuzzy at best |
|
| |
Rail guns perhaps would perform. But there's still the signature. I hope I'm off this rock before The End. |
|
| |
Round would lose penetrating power. |
|
| |
I was thinking this would be a hammer or something. |
|
| |
If you want to get rid of the "crack," suggest some silent launching mechanism, such as a rail gun. Oh, wait, second thoughts, please don't. |
|

It's already been done. The best sniper rifle fires a fifty
caliber round, and has no silencer, as its range is over a
mile. Look it up - it's called a Barrett M82A1 .50 Caliber
'Light Fifty'. Apart from that, inventing new weapons is
just boring, unless they do interesting things, which this
doesn't really. |
|
| |
The heavier round could help slightly since it would reduce air resistance effects. Although the recoil would also be increased. |
|
| |
You could always fire miniature rockets (which acted against gravity) to keep the range up. Or just include a handy range finder and inclination look-up table with your mor^h^h^hgun. |
|

I can throw an eight pound brick, or equivalent stone, about 75 yards with a sling. Works best if you are aiming down hill. Accuracy? I can land the rock in or near that patch of trees down there. Lethality? Well, if something is under the rock, it's gonna take a quite a wallop. I don't think I've ever killed anything, but I have torn some limbs off trees and scared the bejeezus out of a few deer. |
|
| |
I can shoot a one ounce watermelon seed, or equivalent pumpkin seed, about 150 yards with only the pressure of two apposing parts of my body. Accuracy? I'll put your eye out and laugh like a loon! Lethality? I kill stuff all the time, without even trying. Yeah! So there! |
|
| |
First let me say I know the fishbones are coming because a slower, more massive bullet is less lethal and less accurate. |

DeLisle Carbine (see Link) - I was so entrigued by the weapon that I went ahead and built my own non-silenced version from a SMLE No.4 Mk 1 with a 20" heavy barrel. I wish I could post a picture it turned out so nice. Yes, I can place normal .45 ACP rounds more accurately since it has a scope, but the real fun is in increasing the horsepower, not slowing it down and silencing it. I handload ammo that shoots a 230 grain bullet at 1575 fps - never want to accidentally shoot that in a pistol. |
|
| |
I also handload 12 gauge shotgun slugs - 525 grains of lead at ~1,700 fps... You could decrease the load to make it subsonic if you really wanted to - kind of like a fishing sinker from hell. |
|
| |
Basically the slow&heavy concept can be incredibly devastating - just ask the folks shot during the American Civil War. A 500+ grain soft lead slug at subsonic velocities packs a big punch. |
|
| |
//Yeah, that's why they use .17 calibre rifles, with 3800fps muzzle velocity to shoot elephants.//
It would have to be a very skinny elephant to fit inside the barrel of a .17 calibre rifle. Or do they slide the elephant into the barrel trunk first and leave the main body poking out of the end like with rifle grenades? |
|
| |
They use .17 for large game? That's just weird. The .220 Swift and the rare .220 Rocket are even faster then the .17 and they are considered a small game or "varmint" round. Exceptionally accurate, though, except easily deflected by twigs, leaves and wind. |
|
| |
[DrBob], I've never shot an elephant before, and if that's the rig I'm expected to use, I'm going to stick to shooting fish. |
|
| |
//general infantry uses .556// Not unless they also employ beaters and bearers. I think you meant 5.56mm. |
|
| |
Ooops. I don't ever mean to carve anyone, especially my UnaBubba. |
|
| |
feh, as usual, the majority of the things I think of while drunk shouldn't be let out for the rest of the world to hear. God I hate having so little of a life that I get drunk just to make HB more entertaining |
|
| |
I wouldn't be so harsh on yourself, Scott. There exists a range of rounds called "whisper", the most popular of which is the .300 whisper, which is a .223 (5.56mm) round necked out to fire a very heavy .300" bullet, at subsonic velocity. |
|
| |
It can be supressed quite nicely (BTW silencing subsonic heavy gauge weapons is easy: 7.62mm bore is smaller than a .45 bore, for which many supressor designs exist.....). |
|
| |
Same company makes .500 whisper rounds for supressed sniper rifles. A big, heavy round with a very precise trajectory means no accuracy problems out to several hundred yards. A 350 odd grain .50 calibre bullet even at subsonic velocities has no trouble penetrating body armour. think about a .50 cal (M2) round at about two miles or so range. |

Check out the 0.50 Beowulf, a rather new addition. It's rated for dangerous game, like bear <although I'll never understand why someone would want to shoot a bear :( > |
