So, being more of a small game hunter & paper puncher, help me understand the diversion from 6.5CM to velocity vs energy by looking at two extreme cases.
One, a 5.56 with a 55gr bullet has a MV of around 3,000 - 3,200 and a ME of around 1,000 - 1,200 ft-lbs.
Two, a .470 Nitro Express with a 500 gr bullet has a MV of around 2,150 fps and a ME of around 5,100 ft-lbs.
Assume the bullets are of similar build, solids or thin jackets, whatever. And let's not consider trajectory for the moment.
Shoot 150 lb thin-skinned deer with both calibers, using similar thin jacketed soft points. Which kills deer “deader”: the 3,000 fps bullet, or the 5,000 ft-lbs of energy bullet?
Switch to a thick-skinned elephant or rhino. Does a 55 gr solid or a 500 gr solid at those same velocities kill better?
Do these extremes suggest that maybe velocity isn’t all that matters? ‘Cause I didn’t see any qualifiers other than the velocity or energy.
Just asking.
