Never shot one and I’ve only seen them shot at an indoor range with ear protection on so I can’t even comment on the muzzle report either. I was just going on of what guys have told me about their recoil/reliability. I feel like anything shot indoors is going to suck for your ear drums lol.
Back in the 60's when I didn't know any better I fired 8mm Mausers and 30-30's and 12 gauge shotguns and a 38 Special and a 45 Auto sometimes without ear protection but other times I'd use cigarette butts and this was all outdoors and it made my ears ring but it wasn't bad.
But one time years later I fired a 30 Carbine Blackhawk with a 7 1/2 inch barrel outdoors and I was with a bunch of guys and we were taking a break at the top of a hill with the back stop behind us and we all had our earplugs out. That day we were shooting at old bowling balls to see which gun would do the most damage and one of us got teh bright idea to roll one down the hill and we all drew our guns and started blasting away at it with out putting on our ear plugs.
I immediately lost 90 percent of my hearing and it didn't come back for six hours and my ears were hurting and ringing after that all the next day. The temporary hearing loss was first of all, troubling, because I wasn't sure if it was ever going to come back, but also disorienting and effected my balance an made me nauseous. I also began to lose my hearing in my 60's and now in my 70's I wear hearing aids today but I don't think it was just that one incident but I'm sure it didn't do me any good.
So yes, all guns ar loud but some a LOT louder than others as measured in decibels. You can read reports on the decible levels of different guns but the figures are never exact because it differs with barrel length and indificual guns.
But the reason why some guns are a LOT louder than others is because decibels are measured on a logarithmic rather than a linear scale and a gun that is 3 decibels louder produces TWICE the sonic energy.
Here's a table showing the estimated decibel levels of certain calibers and I already see one obvious error and that is that they are estimating the decibel level of 22 pistol or rifle rto be teh sam while most other sources say that the 22 pistol is at least 3 decibels higher than a 22 rifle and anyone who has shot both, know that the pistol is louder than the rifle.
