Its hard to say, it depends on the construction of the bullet more than velocity.īut if we are comparing two FMJ bullets but different grain weights and velocities, yes, the lighter bullet is more likely to destabilize in any media and be subjected to higher shear stress causing it to break apart and dump energy faster, while the heavier slower bullet will holder together and remain more stable for longer.
Nobody has ever come close to presenting an argument to me that would convince me to willingly give up rifle performance for SD use. I've taken game with rifles, pistols, bows and shotguns and seen firsthand the terminal effects of each. If you have a rifle in your hands, might as well wring all the performance you can from it. Don't get me wrong 45 is a killer and I love mine, but it's not going to put danger on the ground the way a rifle round is. You're talking about downgrading from pretty damn good rifle terminal performance to slightly spicy 45aarp. And to top it all off with a can even 556 isn't going to disorient the shooter, much less 300blk. Your not going to regret suppers with our without a can when your arms aren't being ripped off by a methed out assailant you've already ventilated 8 times. But in the end penetration isn't strictly about energy.Īs far as keeping your ears safe vs shooting effective threat stoppers. Heavier traditional bullets tend to be constructed tougher. And as another has stated it probably has more to do with bullet construction. There have been hundreds maybe thousands of other tests, many sponsored by dod and law enforcement agencies that suggest that the opposite is generally true. Yes, it can be painful, and yes you could have significantly reduced hearing for a short amount of time while your eardrum heals, but the permanent damage slowly accumulates. And they’ll only be slightly higher than what’s considered hearing safe (exposure time matters for this too).Īll in all, the hearing damage from a short exposure to loud sounds like gun shots isn’t as bad as people make it out to be. They will likely be below the pain threshold for your ears.

They won’t be movie quiet like subs, but they won’t rupture your eardrums. If you add a silencer, even supers aren’t that bad. It’s not like you’re going to have massively reduced hearing from one self defense encounter. Yes, you will have permanent hearing damage, but damage from a single unsuppressed rifle gunshot has about the hearing damage as a work week of exposure to loud background noises like machinery, or loud A/Cs. You will likely rupture an eardrum, but that heals. Some things to think about in terms of sound and hearing damage though:Įven without a silencer, a couple supersonic loads shot in your house isn’t the end of the world. A rifle load just gives you a slightly bigger margin of error. Single shot from a 9mm carbine and he was instantly incapacitated. Heck, look at the video or the two guys arguing over custody on one guy’s front step. With a vital zone shot, they will be in hypovolemic shock quickly. Even if the sub only does crush damage, you have a 1” wide face cruising through the body with those expanded petals. They’re better than 9mm or even 45, but way more controllable in a braced AR pistol. I personally think subs are totally fine for home defense.
