Just for fun more than anything. I'll start (and add later):
In this clip, at 4:07, FW claims that "[the .408 Cheytac] has more kinetic energy past 400 yards than a .50 cal round". So let's test that claim:
.408 Cheytac at 500 yards
BC= .945 (419 gr bullet)
MV= 3,000 fps
Bullet weight= 419 gr
Vel @ 500= 2,505 fps
Energy @ 500= 5,841 ft.-lbs
.50 BMG at 500 yards
BC=1.050 (Hornady A-Max)
MV= 2,618 fps
Bullet Weight = 750 gr
Vel @ 500= 2,206
Energy @ 500= 8,106 ft-lbs.
So, not only is the claim not true, but the .50 BMG actually has 39.77% MORE energy at 500 yards than the .408 Chey-Tac, and the percentage only get larger from there on out with increasing distance due to the better bullet BC. The claim is also not even close to being true at 400 or 401 yards or any other distance. And these numbers are *IF* you believe the claimed MV of 3,000 fps for the 419 gr .408 cheytac.
There are lots of others out there - let's find them. The show is filled with unbelievable hyperbole and truth-stretching.
