There was a discussion about this recently on ammosmith.com There was a link to a magazine article. Hodgdon lists one load with only a tiny bit of powder, Clays IIRC.
I would like to know if it is feasible to lighten up the spring on an AR to allow it to function with sub-sonic ammo.. I have some back yard vermin to deal with. |

Lightening up the spring will do nothing....there isnt enough gas pressure to operate the system....U could probably severly modify yer gun to work with sub loads, light weight carrier, main spring, open up gas port might work....Or u could invest in a 22lr conversion kit. |

I created some loads with 50 grain Varmint Gernades and approx 7-8 grains of Varget. OAL I cannot recall but it was similar to a factory load. Just adjust your powder until you get what you want out of the round. Alot of guys adjust OAL but that creates a whole new load. Keep it simple and work on the powder.

I found this thread on page 2. People ask this question all the time, and give the same reasons. Varmints, squirrels, etc. Having been interested in this concept in the past, I did some research. My conclusion on the subject is that if you want to shoot subsonic .223 then you might as well be shooting .22LR 60gr Aguila SSS.

Short answer: No. It has been tried with great effort to get the AR to operate on subsonic .223. If you came up with a repeatable working system you could probably retire. jonblack |

I just realized that you were the OP in the thread I linked to above, which is a dupe of this thread. Did you not find the info you needed in that thread? .223 Subsonics Subsonic .223 is serious business jonblack |
