I just recently looked at some of my .30 caliber M1 Carbine ammo and noticed that they were not crimped. I have Remington, S&B, Aguila and none of it is military crimped. Most of this ammo was bought in 2010- 2013. I would like to know what other military ammo designation is not crimped and why the .30 Carbine isn't crimped? This is just for my info. Guess I have found out my answer with a google search.
