• Subsonic 5.56 loads?

Posted: **Wed Feb 25, 2009 12:18 pm**

Hey guys,
I am new to this site and I am trying to find a load for my Dpms flat top with an AAC M4-2000, something that is subsonic hopefully?

I don't know a load that will cycle a normal gun and is subsonic.

If you want to make a subsonic round, it can be done with trailboss powder.

But honestly, I don't think it is worth it. Buy a 22LR kit for semi-auto fire. If you need 1 round of subsonic and then regular ammo, they make sigle round conversions.

.22lr is 40 grain. 5.56mm subsonic is 80+ grain and much lower drag. It may be worth it.

OK, IMHO not worth it.

Unless you have a special barrel an 80gr bullet will tumble.
If you want a heavier bullet you might want to try Aguila SSS 60gr bullets.

And on that note

The Suppressor guy at my gun shop recommended Engel Balistic Research. I have not ordered any of these because I don't have my .223 can yet but as soon as I get it I plan on placing an order for the EBR ammo.

I have looked into that EBR ammo, that is the reason I wanted to try some handloads because EBR is around $30-$40 per 20 rounds. At that rate I could shoot all of one hour before I broke the bank

On a side note I did look around here and found some good handloads.

What would a combat load .223 with a good suppressor sound like? Here, it sounds like an ordinary .22lr.

Good god man.. What are you hunting where you are going through that much ammo???

I just ordered 2 boxes of EBR ammo today. If my Form 4 ever comes back I'll go out and shoot it with my M42K on my gas piston AR.

Google Seafire Blue Dot Loads

He's done a lot of work with .223 (amongst other calibers) and subsonic loads and has a fair amount of different weight bullets using Blue Dot. I've tried a few myself and they are very accurate and very quiet.
