maybe we just expect to much out of .380
Maybe....personally, I view the .380 acp as a sort of .38 special "light".
But ME and velocity are indications of what penetration might be expected,
Nope - only in a roundabout way doe they matter.
Where penetration is concerned, sectional density is - and will always be - king of the hill.
An arrow weighing 400 to 500 grains with a sectional density of ~ .698psi shot at 300 fps will out-penetrate a 180 grain .30/06 bullet @ over 2500 fps.
Don't believe it?
Shoot a sack of grain w/a .30/06 & the bullet stops in it.
Superglue a similar bullet to the shaft of an arrow and shot that sack & the bullet comes out the other side.
Velocity will deliver a higher ME & a flatter trajectory.
The drawback to higher velocity is - - it can and often will, cause the bullet to expand. When a nominal bullet, such as a 95 grain, .355" bullet with a dismal SD of .108psi expands, it causes the SD figure & thus penetration, to go down.
That in itself is neither good or bad.
Controlled expansion is a good thing
expansion just for the sake of expansionis a bad thing.
Didn't you read my post that we only got 774 fps with the Hornady FTX?
It was even worse than the Federal Hydroshocks!
And your point here is what?
774 fps is a fair velocity - considering that you really only need between 300 and 500 to be considered lethal.
774 is also quite a bit quicker than the .44 russian and/or the .44 sp (246 gr), the .38 S&W, .455 Webley - and quite a few other traditional service type rounds - that have fair to good reputations for getting the job done.
The whole topic is - - convoluted at best & complicated more by the companies that lure people in with misleading (but 100% true) ME and velocity figures.
Targetsport has aguila 1k for 200 free shipping which is a good deal for .380 but Im wondering how long is it gonna take me to shoot 1k rounds out of a little .380 pocket gun.. probably last me 2 years lol.
Where are you in Ohio? I just recently got my Ruger LCP & it looks like it's going to be my go-to carry gun. I quit shooting .380 years ago (when the small "pocket 9's" first came about). I might be interested in going halves with you on some.
