Same here but I just had to get the T97 and the ammo for it.
She seemed surprisingly nice about the whole thing but did mention something about getting 4 pairs of shoes... :confused:
Squeaked by and just got the $289 price on the 5.56 mm ammo and a price match on some more 9mm ammo.
Life is good.:)
 
Received mine today, looks just as good as all my AE and shoots great. Seems like it's a bit hotter than the AE, probably cause its 5.56. I never bought 5.56 before.
 
Has anyone done up a full ballistic/trajectory table for this ammo? I think someone posted chronograph measurements before, but I don't recall seeing a full trajectory range post. It's hotter than commercial .223 ammo so I was just wondering about the differences in longer range trajectory. I've only popped one cartridge of this stuff so far.
 
It would make a difference what barrel length you have and if it's semi auto or bolt.
However I too would love a table. I wonder how close it is to domestic stuff.
 
I'll run some over the chrony next time I'm out....longest barrel I got is 16" though.
I doubt its excessively hot.....doesn't have any flash suppressant in the powder for sure....muzzle flash is ridiculous....

OK, so if one can determine a ballistic coefficient for the bullet, could not a full trajectory table be generated with some of the online ballistics programs and physically checked out at longer ranges? Granted, the differences between this and commercial .223 ammo is likely less than the variance of shooters skills and this surplus ammo isn't what you might want to rely on for long range bullseye type shooting anyway. Just interested in what magnitude of difference there actually might be (more on an academic level I guess).

Use .243 ballistic coefficient. The norinco ammo is 2 moa out of my Tavor.
 
I can't recall what lot number I have but I've shot at least a hundred rounds and all the brass looked just fine after shooting.
