Thanks to all of you for all your advice. I just bought a SCAR 17s and your input on everything has been invaluable.
Hopefully, this is a helpful bit of info back at you. gunbot.net has pricing for all types of ammo from all types of vendors WITH THE PRICE PER ROUND AVERAGE. If you're like me, this is a HUGE help and saves multiple windows and lots of time. It also breaks out the grade of ammo. I just bought military surplus .308 for $.64/rd.
