3/4" Thick Steel Vs. .308 Win
I now have a 3/4" thick piece of steel ready for testing:
Do you think this will be able to stand up to a .308?
Those of you who are up to date on your physics and calculus can just do a little math and figure out what will happen.
Here is the data required for the calculation:
The steel plate in question is actually 3 pieces of 1/4" thick ASTM A36 welded together.
The mechanical properties of which are:
Yield Strength: 248 MPa
Tensile Strength: 400 MPa
Young's Modulus 200 GPa
Shear Modulus 70 GPa
Poisson's Ratio 0.26
Density 7861 kg/(m^3)
The bullet specs are:
Composition: Copper jacketed lead
Weight: 150 grains
Velocity @ 100 yards: 2533 fps
Energy @ 100 yards: 2137 ft-lbs
I posted all these numbers because I'm sure that Ben will be able to determine precisely what the outcome will be.
I could do the math too...if I wanted to...but I don't want to spoil the surprise.
What do you think will happen when I shoot it?
Will it:
-Bounce off leaving the plate unscathed.
-Make a dent but fail to penetrate.
-Punch right through.
-or something else?
...shooting stuff is fun.
