Anybody need some good brass 5.56?

can someone go over differences between shooting 5.56 over .223? is differences negligible? i think i read 5.56 shoot hotter so could be more wear and tear over time.

another $220 down the pipe. 24 cent rounds free shipping really is a great deal.

PMC Xtac or something is the only other .223 ammo i've shot. never had a problem with any of it yet.

I have a Ruger American Predator in .223 Remington and I was told not to shoot 5.56.

The Ruger ARs are rated for 5.56.

Ammo is virtually identical, 5.56 NATO uses brass that is slightly thicker in some areas which accounts for the higher pressure. Military ammo is also heavily crimped and uses sealant. The difference in wear and tear between a diet of M855, M193, and commercial .223 ammo is negligible. M855A1 is a different story there but nobody but the military is shooting enough of it to show the damage. I also suspect that a lot of the broken bolts and other things being reported are in higher round count rifles and those not using the EPR magazines. 5.56 chambered rifles have slightly different chamber dimensions compared to a .223 to mitigate potential pressure spikes and increase reliability.

you can shoot .223 in a 5.56.

You can not shoot 5.56 in a .223.

Well you could and probably 100 rounds wouldn't matter. But, the one time that it does....

Thanks for the heads up. Can't pass that up.
