I'm not a noob to guns, but I'm new to the AR platform. I'm going to be getting my first soon and I've been keeping my eyes on ammo prices. Unfortunately, they seem to vary somewhat widely, not something I'm quite used to with other types of ammo. So, I'm wondering, what's a good price per round for AR ammo. I'm talking about your standard plinking/target ammo - FMJ type like XM193. I've seen prices from a low for Federal Xm193 at around .25 a round (on sale) to over .50 a round for similar, sometimes even the exact same ammo. What you consider the 'average' for .223/5.56 rounds like this? Thanks in advance for your wise insight I know I'm asking the right folks here.
