If someone cuts their range time in half and leaves because they think it's too noisy, that's more than "just making an observation." That's taking action. If someone has to step back from the firing line and cover their ear protection with their hands, that isn't simply "making an observation."
Then perhaps he should have complained to the range officer. Doesn't do one bit of good to complain about it here.
But I'd advise against complaining to another shooter about their gun being "too noisy".
He's making an observation to US on the forum.
As far as the range,
Leaving early or holding your ears isn't rude.
If my hearing protection wasn't adequate i would likely roll early too. Haven't we all cut a trip short for some reason or another.
Did what he had to do without causing any trouble..
Didn't find what he said complaining at all on here. I see that you do which is fine. But i think i might give him the benefit of the doubt.
Gotta ask why would he complain to the range??
