I am waiting on a AAC M4 1000 for a Rem 700 in 223. I am wanting to stock up on some subsonic ammo. Can I get some sources for ammo in stock for purchase and some recommendations?

Thanks

Get a spikes conversion and run Aguila SSS for the same effect.

60 Gr sub sonic bullet.

I know the case is smaller but all the 5.56 sub is, is a 55-75 Gr subsonic.

As a general rule, I agree with BJ above me.
 
Re: Subsonic 223 Ammo

I load my own 223, subsonic included. I think it is very much worth the time and expense. I would not buy it though as it is not worth it. I use speer 70 grain (6.5 gr H110) in my 1-8 twist AR-15. It is cheap and accurate enough. No way is subsonic in an supressed AR-15 less noisy than a suppressed 10/22 using subsonic ammo though. Not even close in my experience.

The speer 70 grain is much better than a 22lr upper shooting 40 grain at 1050 fps or 60 grain Aguila at 700 fps. Compare 171 ft-lbs from the 70 grain against 98 ft-lbs for the 40 grain and 65 ft-lbs for the 60 grain SSS.

Re: Subsonic 223 Ammo

I had no idea on the ft lbs jump. I don't load my own so I haven't found the cost to benefit ratio reasonable. What kind of accuracy do you get?
 
Re: Subsonic 223 Ammo

My subsonic 223 does not cycle on my ar-15, not even with an empty buffer tube and cut down spring. I have read claims of subsonic 223 cycling a standard ar-15 rifle setup, but never seen in person or on video. Accuracy is 3 moa so far in my load development. I hope to get down to 2 or less.

In the .223 caliber rifle just use your silencer on a .22lr if you want subsonic. Your .223 bolt gun will be plenty quiet enough with full power ammo.

In larger bore rifles subsonic becomes worth the effort.

I agree. I shoot subsonic in 300/338/510 whispers (single shots) as well as the 458 socom on an ar-15. The socom is rather loud as the bore has to be large. Adding in the action noise makes it a bit loud for shooting without ear plugs. The 300 whisper in an ar-15 sounds ok too, not as good as the single shots though.

FYI, this came up in a Google search. There seems to be no way to get to it on their site. Subsonic loads are listed on the bottom.

Engel Ballistic. It does not cycle the action but it is apparently very good ammo. And pricey too.
