Sub-Sonic 147 grain 357 Sig round?

Discussion in 'TOP GUNS *357 Sig* Club' started by skip a stone, Jan 2, 2010.

  1. Is there anyone out there that has a reciepe (sp) or powder combo that will push a 147 grain bullet out of a 357 Sig case just under the sound barrier, so I could use a suppressor without going with a .40/9mm conversion barrel?

    For some reason I have had the absolute worse luck with those .40/9mm barrels, and have nothing but failure to feed, stovepiping, and all manner of jams imaginable.

    Figure it's possible to use a real weak powder and compress the bullet up and into the powder to enhance reliable bullet seating and to avoid bullet setback?
     
  2. not trying to be a wise ass, but wouldn't a subsonic 147gr .357 SIG round just be the same thing as a 147gr 9mm round? that nullifies all the benefits of using the .357...
     


  3. Don't worry about being a wise ass with me, I don't really mind. I was just curious if there was a handload that would get a 357 Sig to perform and behave consistantly like a subsonic 9mm. That was the whole point of my question, so I could screw on a supressor to my 357 Sig barrel and pop off real quiet like, after sending off for the 200+ paperwork to allow me to have a supressor legally that is. The 357 Sig is just a super charged 9mm, both use a .355 (that's why you will never see me put a decimal point in front of 357 Sig in any of my posts) caliber bullet, so using a 9mm supressor should work. The rest would just come down to using...uh, for lack of a better term...unfast 357 Sig rounds when shooting in quiet mode. I thought my post was pretty clear on this, but I appologize for any confusion I may have caused.
     
  4. no i understood your question, i just couldn't figure out why you would want to use a subsonic .357 SIG round for suppressor use when you could just use the 147gr 9mm rounds which are already subsonic (unless you don't have a 9mm handgun). if all you have is a 357 that would explain it.
