Is your .223 rifle an AR? With a flash suppressor?
If so, I truly feel your pain. I went to my nearby range, to target practice, and the shooter who set up next to me had an AR, with flash suppressor. The range has a tin roof covering the firing line, and by the time that guy shot 3 or 4 rounds, half the other shooters packed up and left. Because I was using double hearing protection (muffs over ear plugs), I was able to tolerate the noise level - barely. I wasn't having much fun, but that's just the way it goes, sometimes.
So I put away my mild mannered 7X57, and cranked up my 270 WSM
He packed up and left.
