I'm looking for tests or studies on how far out you can penetrate Level III hardplates with the 338 Lapua. Any info you have or can point me toward would be appreciated.

I doubt they would even slow it down.

I've seen what 7.62x54r does to plates. Not pretty when it makes it through the front plate, the body and stops halfway in the back plate

I have no doubt that it would penetrate the plates, but out how far can you depend on a solid kill. I am also working under the assumption the shooter would go for a head shot out to 300'ish depending on conditions like I would. So beyond range am I still going to have solid penetration?

what makes you think they would go for a headshot? if you have a 338 lapua, COM will make plenty a mess and is a much larger target

If someone is pointing a 338LM at you, the first thing you'll know about it is when your head explodes into pulp, your mates around you wonder what the bits of stuff are that's hitting them as the sonic boom eventually catches up and the spotter calmly says to the sniper:

"I wonder how much he paid for that body armour?"

I'd be willing to bet that even though the round might be stopped the impact of the projectile with all the foot pounds behind it could stil kill you. A 690gr .50BMG FMJ at 50 yards is hitting around 2,800 fps and generating roughly 10,000 foot pounds of energy. I'd be willing to guess the fluid shockwaves generated from the impact could/would shatter ribs, shatter spine and destroy internal organs.

This is a good reminder that as powerful as .338 Lapua is, it isn't even in the same stadium as .50 BMG.

Look at it in terms of muzzle energy. The difference explains why, for example, .338 Lapua is OK at our private range, but .50 BMG is not. .50 BMG is just another world compared to any other rifle round.
Link Posted: 12/28/2012 12:05:45 PM EST
I don't think the bullet would notice, nor do I think you could reasonably carry body armor that would stop it. Were it to stop the bullet, you'd probably not feel very sporty for the next week or two.

Lets just say by some mircle your melon is not a fine red splatter of ick, you just took one of the hardest hitting rounds made short of anti tank arty.... I am thinking FUCKING OUCH!

I think it was something like " If you're taking multiple rounds to the torso from a 338 Lapua, body armor is the least of your worries."

I'd say the force it would apply to your body would be sufficient to unplug you - penetration or no.

On a serious note:

Provided that there is no penetration, and there is no protrusion of the vest into the body cavity (meaning that the plate does its job and spreads the impact over the surface area of the plate) the shootee will feel no more impact than the person shooting the rifle.

The plate, pushing into the shootee, being of much greater surface area, will impart LESS psi of pressure than the shooter feels from the butt plate.

It's a provable fact.

ETA: I should've read the origianl question again. I thought we were discussing a plate that would actually stop the round.

That would be the case if the gun in question did not have a brake or suppressor.
