Re: Ar-15 Question
5.56 case walls are thicker and the primers are crimped to handle the higher pressure. I believe the two most common military bullet weights are 55 and 62 grains. For the frugal, like myself, I reload for my AR and prefer the thick walled military brass as the deflector often dents 223 brass. I also reload to keep the gun cleaner with better powders, and us heavier bullets as I have a 1 in 9 twist.
If guns cause crime, mine must be broken.
