Has anyone else done, or does anyone else plan to do...
what I plan to do as my suppressor project?
Which is, thread two gun barrels: 1. Teppo Jutsu .338 spectre upper for AR15 2. 9x19 handgun (in my case CZ75 SP01 tactical) And get & use a 9mm/.35 cal pistol suppressor for both (.338 spectre with subsonic loads only)? Seems like the best way to make your suppressor dollar go a long ways in terms of versatility. The .338 spectre does everything the .300 whisper can do, plus a smidgeon more. Way cool: http://www.teppojutsu.com/ |

That's the oddest looking round I've ever seen...

tee hee, yup.
You use 6.8 SPC mags for it. Ballistics similar to .357 maximum at the muzzle, only with much better ballistic coefficient. Or, or dialed down to a subsonic load @ 1,000-1,050 fps (preferably a 300 gr SMK), for minimal sound, either suppressed or unsuppressed. |

Problem I see is that most, if not all 9mm cans are not designed for the pressures from a rifle round. Granted, I'm unfamiliar with the 338.

MisterPX nailed it. Even 9mm subgun cans built for full auto fire aren't designed to withstand rifle cartridge pressures. You might wanna call AAC or SWR, see what they have to say about it.
Using .30 caliber cans on smaller diameter rifle rounds is pretty common though. Some people claim that firing .223 through a 762SD is quieter than some dedicated .223 cans.

I had assumed (I believe correctly, but perhaps erroneously) that .338 spectre, loaded to subsonic velocities (1,000-1,050) as I said above, would generate about the same amount of pressures as a 9x19 bullet going at the same speed (notwithstanding that the bullet is 250-300 grains, instead of say, 147 gr), and therefore would not be a problem for the pistol suppressor, no?

You could be right, as I have zero knowledge of that particular round. As I said, call AAC or SWR or one of the other manufacturers and run it by them.

FF -
Like the previous posters, I would want to talk to the manufacturer of the can before putting a .338 through a 9mm can. I would think that even though the bullet is moving at roughly the same velocity as a 9mm, there has to be more pressure to drive the heavier bullet at that velocity. I could be wrong, but its not something I'd want to learn the hard way. A phone call is cheap; sending your can back to the manufacturer to get repaired is not. That said, it may work, but I'd want the manufacturer's blessing first. FWIW, the Bowers CAC-9 was never designed for anything but 9mm, but I have a friend who occasionally used his on his M16 (in 5.56, not 9mm) with no problems. |

FWIW, there are several folks over on AR15.com who do exactly what you describe. I'd still make a call to the manufacturer though.

I've heard of people using an AWC MK9 for .300 whisper before with no problems.

Manedwolf:
Look at this pic of the SSK .338 whisper, which is very similar to the .338 spectre: http://www.sskindustries.com/cartridges.htm scroll down about 3/4ths of the way, on the right - anyone know how to copy/paste that picture here? I tried... thanks. And if you think that 300 gr sierra in that case is crazy looking, check out the .510 whisper next to it and up above in the middle - it says MOA accuracy to 600 yards, and under 126 db when suppressed. At that range, you'll have time to take a leak after firing, before looking through your spotting scope to see the bullet get to the target, and it might have dropped a couple dozen feet, but it'll nail the target with a lot of wallop because that 750 gr bullet will still be moving along at roughly the speed of a light .45 acp 230 gr round, due to the insane BC of the 750 Hornady. |
