Re: .223 subsonic
No cycling with subs in an AR.
Secondly... no reason for subs in a 223. You can use a regular 22LR to get the same exact effect. Bullet weights are similar. Subsonic 308 is actually worth it. Subsonic 223 isn't, in my experience.

Re: .223 subsonic
I posted a load in the subsonic section using Trailboss with 75gr. bthp, 5.2 grs as I recall.
You can get an AR to cycle, but it is a lot of work and involves springs and buffers.
Sub loads in .223 can be useful out of a bolt rifle, launching 75 to 90 gr. bullets at 1050 hits harder than 40 gr. at same speed. Costs a lot more with the .223 for marginal increase in performance. Useful when your in the field with your suppressed .223 yote hunting and that pesky skunk, dilllo, etc comes a knocking.

Re: .223 subsonic
You can get the .223 to cycle. I put alot of time and effort into it and I don't have my notes with me here. You have to use a very heavy projo and special canister powder you cannot get at the local gun shop. I made projos in the 100gr range that worked quite well. but cycling an AR action and having sub ammo is well quite stupid to me. The whole purpose of a suppressor is to be quiet, right. Well shoot one rd. of sub ammo then manual cycle the action. Not to quiet huh. Just my .02

Re: .223 subsonic
thanks
I actually have worked out a nice sub load for my .308 using 180g Hornady round nose and as i recall either 10.3 or 10.1grains of Trailboss in LC brass.
Same load has worked well in July and November, I live in Northern Virginia.
thanks

Re: .223 subsonic
Thanks that's helpful.
I posted my .308 sub load and found that a round nose projectile did much better for stability at lower speed. As I developed the load, the low end of the test showed key holing and then everything just settled in and got a pretty good group at 100 yards. Elevation with a 20moa base is somewhere in the 400-500 yard equivalent of shooting a non sub round.

Re: .223 subsonic
Thanks for your comments. I was attempting to find out if anyone had worked one out and the effort involved to get a gas gun to cycle...you are correct it wouldnt be quiet but then again, no sonic boom for neighbors to complain about when shooting. That was my goal.
Thanks again
