 How far out is a .223 SBR accurate?

I have an 11.5" SBR with a suppressor...the longest I have shot it is out to 100 yards. Very accurate. Question....How far out have you guys shot your .223 SBR and how was the accuracy? .223 SBR's get a bad rap because they loose the velocity compared to a 16". I still would not want to get hit by one at 100 or 200 yards. Thanks for any info...

I have a 10.5" that I can hit an11x17 steep target at 300yds without problem
Accurate enough for me

A couple of years ago I shot my M16A1 with its 11½ inch upper at a target 200 yards away. The accuracy was comparable to me shooting its 20 inch upper. I later posted the whole afternoon on Arfcom. The biggest problem I had that day was aiming at two targets and seeing three.

You really don’t have to worry about accuracy until you start talking about pistol length barrel, i.e.; 4 or 6 inch barrels.

I can hit a gallon milk jug at two hundred meters off hand with my 11.5 inch AR SBR. Grapefruit at a hundred yards .... ... I'm working on it... ... a lot. Ronzo

KevinB smoked some dude at 400 or so with his, IIRC.

My 10.5" with Krink is accurate out to at least 300 yards. Good enough for me.

The short barrel does not affect accuracy. (Much ) The biggest effect is lower velocity which translates into a slightly less flat trajectory, and less damage. With the same sight radius or optics I expect similar accuracy, but a different trajectory due to the lower velocity.

We have 18" by 24" plates at 500 yards at my range and I can consistently hit it with a LMT 10.5" with KXC.

We can hit human steelys at 400 yards with a Model1 10.5 NO PROB. ( shoting from a bench helps, Alot)

Welding tank at 450 yds with a 4moa Aimpoint from a rest... no problem.

ETA: 11.5" SBR

At what range does the reduced velocity from the short bbl takes it toll?

It takes a toll at all ranges. The trajectory isn't as flat. Lower velocity means less damage. Out of a 11.5 you might have 25m of fragmentation w/ 55gr ball IIRC, and maybe 12m w/ 62. Most of the people I know w/ SBRs or AR pistols load ballistic tip ammo for defensive purposes.

I dont think Kevin did that, he was standing beside a NSW guy who did that

He is a bit busy right now trying to find all his gear that is spread all over the middle east, perhaps he will post in this thread once he gets settled in.

And if there is any chance that KevinB did do it, I'm sure he was using AMERICAN ammo!

I run 55gr TAP.

For those who posted...what type of ammo were you using? 55gr? 62gr?

1/7 twist SBRs normally run 75 and 77 grn ammo which helps with the accuracy at longer ranges and don't hurt none in helping putting down the target.

I had ICC frangible (55gr @ 200 yds), SA surplus (55 gr @ 300 yds), & TZZ surplus (55gr @ 300 yds).
