As a matter of fact I do have a chronograph, bought it up at deer camp. Will try it out next week. As for the teeny weenie barreled AR, I don't want it cuz I'm not stupid.

I have a chrony, and I refuse to butcher any of my .223's

Once again, you run your mouth without know what you are talking about.

Don't you get tired of being shown to be wrong when you generalize (and insult at the same time)?

:devil:

1) There is a limit to how hot you can load a 5.56mm.
2) Barrel length is crucial to speed, there's no getting arund that.
3) Short barreled, hot loaded 5.56mm weapons are NOT multi-hundred meter target guns, plain and simple.

I cringe to think of the chamber pressures you generate, even with that short a barrel length.

Have a chrono, have as many 10" ARs as you do.
Although my single six has a barrel almost that long. :D

I don't own such, but I have fired, chrono'd, and tested them. When they were built well, the accuracy was suprisingly good.

However, the reliability of 10" and 11.5" barreled CAR's was far below that of 16" and 20" AR-15/M-16/CAR's. The two most reliable types of shorty .223's that I have ever fired were HK G36K's and Ruger AC-556K's.

You often speak of "cans" (suppressors) in conjunction with CAR's. With an unsuppressed shorty .223, you need a suppressor. The muzzle blast is painful, nearly unbearable. The trouble is that suppressors add length and some weight. A suppressed shorty may have military merit, and it sure is fun!

If you really had the experience with the shorty CAR's that you claim, you would almost certainly favor a 14.5" or 16" barrel.

Yes I do have a couple of 10" Barrels, and if you want to only talk about NFA items I also several 11.5" and 14.5" barrels on hand.

There are plently of working chronographs in the shop too, but the ones that see the most usage are the Oehler 35s.

Gunkid I posted the links to sites that not only had chronos but also the cut the barrel down, one inch at a time, to 10 inches a 5.56 and chronographed it! That's PROOF you are so FOS on the subject of the 5.56, velocities, and reloading.

So it is YOU WHO ARE ALL MOUTH. You can talk a talk, but cannot walk any kind of walk.

Hey gunkid/erika, remember reality?? The 14.5" barrel provides a nice game gun or urban rifle under 100 meters.

Out of my 14.5" Armalite M15A2 I chronoed the following;


Swiss GP 90, 62 grain FMJ: average MV 2746.8 & 2734.4 FPS

Cdn C77 Ball, 62 grain FMJ: average MV 2779.9 & 2846.7 FPS

Speer 62 grain FMJBT, 24.5 grains IMR 4895: 2647.1 & 2659.5 FPS

Hornady 68 grain BTHP Match, 24.5 grains IMR 4895: 2616.7 & 2605.5 FPS

Sierra 69 grain HPBT Match, 24.5 grains IMR 4895: 2586.8 & 2578.6 FPS

Remington 55 grain MC: 2856.2 FPS

Please detail your load data, cartridge case, primer, propellant, OAL, etc and the date you chronoed them. Or are you too lazy, inept, stupid and cheap to do it??

And with at 10" or 11" POSCAR drop those figures down by at least 100 FPS! Truely the 11" POSCAR is a real POS!!! The 69 gr Sierra at 2485 makes a 30/30 look GOOD, real GOOD!
