223 subsonic ammo that cycles full#

Can it be done What needs to happen Reply Save Like 1 - 9 of 9 Posts Brandon My brother just got his can yesterday and wants to dedicate an AR to running subsonic. Here are a couple of the guns I mount it on as pictures speak a thousand words. Building an AR (223/5.56) for subsonic reliability- cycling, feeding, etc. 223 match and bthp loads that fly around 2700-2780fps (would have to chronograph my 14.5in 5R POF) would be any quieter? I shouldn't have such a big gap in sound suppression between calibers in this can should I? SO I guess my question to all this boils down to what are the quietest loads 5.56/.223 you have experience with out of a suppressor? Im wondering if the 75-77gr. 223 was muzzling about 3220fps vs the 2680 or so out of my 18in bolt gun. One, the 7.62 suppressor lets out more gas when shooting.

I started to think about it a little more and I had some theories I suppose.

223 would be so much more load through the 7.62 can than even the full power 168-175gr full power. 22mag equivalent maybe? I was somewhat shocked that 55gr. I got to tell you, although I would certainly say you dont 'need' hearing protection, it did indeed still have a pop. Well I figured since I already have my 7.62 can (A YHM 7.62 QD SS) I'd put on the yhm 5.56 mount and run some rounds through it. I have a 300BLK SBR upper that we all know is quiet and subsonic. I have a couple of rigs I have been shooting, hunting, and just plain playing with that are quite fun with my suppressors.
