Federal 6.5 Backcountry?

[RME]

Im not arguing the physics, just saying that you are arguing an academic non issue as most people will run a can and/or hearing protection with short 6.5CM, and folks are shooting bigger calibers with far more muzzle blast. Also, and please stop experimenting on yourself, I'm worried for your well being.

I was thinking the same thing. I've shot thousands of rounds from specialty pistols with 10-15" barrels and I have no idea what they sound like because I've never touched off a round hunting or otherwise without ear pro. I used to hunt with too many deaf, "one shot won't hurt", guys to not protect my ears.

I found myself in front, but a little to the side of a Abrams in Iraq. Those 7 rounds without hearing protection hurt and had a bit of an effect!
