Re: Attempted robbery at Dixie Gun and Pawn: 1911 saves the day!

Yep - which is why it's not about energy alone but how that energy is applied to the tissues via the projectile.

Re: Attempted robbery at Dixie Gun and Pawn: 1911 saves the day!

Absolutely - but my example is to illustrate that it doesn't require a lot of kinetic energy to do a lot of damage.

Re: Attempted robbery at Dixie Gun and Pawn: 1911 saves the day!

I'd sure hate to take a broadhead through my chest-cavity - eish! I have no idea what the volume of the permanent cavity would be, but I'd bet it's spectacular.

Well, knockdown power doesn't exist but for grins I calculated kinetic energies for these calibers, rounded up to 3 decimal places for easier reading:

230gr .45acp @ 900 fps:

230gr = 0.0149037 kg
900 fps = 274.32 m/sec
Ek = 560.763 Joules


115gr 9mm @ 1200 fps:

115gr = 0.00745187 kg
1200 fps = 365.76 m/sec
Ek = 498.457 Joules


125gr .357 Sig @ 1500 fps:

125gr = 0.00809986 kg
1500 fps = 457.2 m/sec
Ek = 846.564 Joules


Very impressive, huh? Not so fast. Let's take this object:

500gr = 0.0323995 kg
220fps = 67.056 m/sec
Ek = 72.842 Joules

Pretty weak, huh? Well... it's a 500gr broadhead arrow @ 220 fps.

As I've always said - ain't about the energy per se - it's how that energy is used to cause physical damage.

I wouldn't bet against you in that analysis.

Re: Attempted robbery at Dixie Gun and Pawn: 1911 saves the day!

When applied to handguns (and rifles and shotguns), it's untrue. When the day comes that we can launch a 5-ton wrecking-ball into someone's chest from the pistol we carry, I'll concede the point ;-)

And especially if he was shooting a 130 grain bullet with a charge that just barely made a 125 power factor. :shock:
I'm going to pray that God will forgive you guys for this. He probably won't, but I'm going to try anyway.

Boom - splat.

:anamatedbanana

As for the smoke - my guess is simply residue on the camera's lens; it's not moving.
