Sniper, Higher chamber pressure to me means there is more power behind the 5.56 than the .223? It sounds like the 5.56 is the magnum version of the .223.
In any case, if there were 2 otherwise identical rifles, one in .223 and one in 5.56, how much more would you pay to get the 5.56?
I'm not sure I would pay more than $25 for the 5.56 rating.
*goes and does some quick research*
OK! Maybe I am willing to pay a little more for a 5.56 gun because it is designed for better accuracy.
"NATO chambers have a long leade1. SAAMI chambers are tighter and have a short leade. SAAMI chambers are designed for increased accuracy, but will yield dangerously high pressures in guns using military ammunition and/or which are subject to high volume shooting. Under such high pressures, a primer may back out completely, drop into the action and cause the firearm to stop working."
Does this mean, in my 5.56 Spikes AR-15 that I should get better accuracy if I use 5.56 ammo instead of .223?
