Re: How loud is a 5.56 through a 7.62 Can?
Also consider the tone of a report. Absolute dB readings are fine, but most of us perceive sounds differently, probably based on what part of our hearing works best. This is not to say that you should shoot loud cans without hearing protection! Just that each host, ammo, weather condition, etc. makes things sound just a bit different from the last.
Without a sound meter, only your ear will tell you whether or not you like a certain can on a certain gun with that particular ammo (again, please not I am not talking about hearing-safe, just preference). For example, some people like the low tone of Elite Iron cans. Others prefer the tinny sound of titanium units. Me, I like the big volume cans on ARs because of the decreased gas in my face. I usually have (and supply to others) plugs in when I am around other shooters, since they can sneak in the unsupressed shot that always seems to ruin my day/demo.
