Average AR15 effective range.

I use my .223 for range plinking only. It is not my favorite calibre, it's weak. Don't read into it too much. I've had enough .223. I like the punch and power of a 6.8spc or .308. Frankly, these calibres are obviously more effective and there is no argument: they're bigger. They are far more enjoyable under all circumstances as well in my opinion. Have a good one guys!

What, the 6.8 SPC is superior to any .223 in every way possible! Even though I've never seen a rifle chambered in it, nevertheless shot one, I know it is way, way better than any other possible service rifle round! How dare you!!! :mad:








:p
 
I'll jump in with this...

The 6.8 SPC is a comprimise cartidge designed in part to provide improved terminal balistic performance in short barreled rifles, whilst being limited to the form-factor of the standard AR-15/M-16/C-7/M-4 magazine well. It is not an "ideal" cartridge, it is the best they could fit into the limited space they had.

There may be more to it than that, but there's my take on it.

The only time I've seen bullets actually tumble out of an AR barrel involved a .22 rimfire kit, a 1/7 barrel, and a bad case of leading inside the bore (I was able to practically scrape chunks out.)

NS
 
baaaaa haaaaaaa

6.8 SPR is that a necked down 30-30 that had the rim removed ???? oh wait yes it is :D


now the Brits had a trial round in 6.25mm based on the 280 Enfield round that was interesting
 
I just got back in the office after a trip to Ft. Benning and Ft. Meade.

There is a lot of Government testing with both real targets and dopler radar reports and bullets and trajectory, and everyone I have seen has not had made any indication the bullet tumbles at any range prior to hitting some sort of media...


I dont really know what to say here beyond your wrong.

1) MARK your mags -- I tend to write KSB #XX on mine
Mags are an expendable item, and tend to be the weakest issue in the M16FOW (M16 Family of Weapons - which the C7 and C8 variants fall into).
2) Keep a round count - even if its not 100% accurate it will give you a good idea, and shocker you can give info the to the weapons techs.

I had a C9 years ago that was an utter POS after being involved in a RTA - it sailed about 25ft off the Grizzy and was imbeded barrel first in the highway to Suffield. It took time, but eventually I learned to articulate the issues on the N/S tag and the weapon was pulled and replaced (the trunion had actually moved in the weapon, and the bolt barrel lockup where out of the proper geometery).

The weapon system is the finest system available available to a Military. The only issues are operator or maintenance, often both.
 
That I'm aware of there at least 2x (probably 3) Bisley Team shooters, 1xQM (not Quarter Master), half a dozen guys with serious combat time, and 1 factory rep/trainer/combat vet with access to the absolute state of the art in real time balistics monitoring saying the 5.56 doesn't tumble. I'd be good with that, but I'm just a civvy. Incidently, I have seen targets shot with 7.62x51 where the bullets were keyholing, but that was a very early FN (Belgian) and the twist rate was subsequently changed to improve stability.
 
I have seen 5.56 rounds tumble BADLY at close range, but it's been related to the launcher, not the bullet so much...at least not until really long distances.

For instance, using my old ar15, I could get almost any .223 bullet out to at least a half kilometer and they were not tumbling. But if I ditched the AR15 and went with my ARM, they'd sometimes be tumbling in under 10 meters.

Even so, I ultimately sold off that ar15 and kept both my arms, and have no intention of getting rid of them. Even though they're less accurate, a decent arm is truly something no shooter should be without if they can avoid it. If nothing else, they make shooting your other guns much easier.
