Crystal,
There is still fair prices for 5.56 out there. My neighbor just purchased 420 rounds, 62 gr, green tip, on stripper clips and in a military can for $200-. 48? is still a little steep for me but cheaper than what I see on gunbroker.com.
Maybe sell half of your steel cased ammo and hold the money till the prices come down. Then buy brass. Just thinking out loud.
