Not knowing the laws of physics doesn't change the laws of physics.
I did some math for the less knowledgeable in the audience. Let's compare a 30-cal 150gr TSX to a 200gr ELD-X from a 300 WM at book max loads from Alliant. 150gr starts out at 3316 fps, 200gr at 2932 fps. The 200gr has a 155 ft lb energy advantage at the muzzle, not a whole lot. But we don't usually shoot animals at the muzzle so muzzle energy and velocity don't matter. What matters is energy and velocity at impact, correct?
150 grain TSX at 3316 fps
Distance Velocity Energy Drop Wind Drift at 10mph
100y 3032 3060 +1.5 0.7
200y 2765 2546 +0.9 3.0
300y 2513 2104 -4.3 7.2
400y 2276 1726 -15 13
500y 2052 1402 -33 22
200 grain ELD-X at 2932 fps
Distance Velocity Energy Drop Wind Drift at 10mph
100y 2786 3446 +1.5 0.5
200y 2644 3103 +0.2 1.9
300y 2505 2787 -6.0 4.4
400y 2371 2496 -18 8
500y 2241 2230 -36 13
Looks like the 200gr ELD-X carries 22% more energy at 200 yards and 32% more energy at 300 yards than the 150gr TSX. That's significant. And is able to dump more of that energy inside the animal. The velocities are almost identical at 300. By 400 yards the 200gr is head and shoulders above the 150gr. And that's the lesson for the "most hunters [who] have never heard of BC". We should teach them instead of pretending it doesn't matter. Sure, I'm losing bullet weight in the animal but that lost bullet weight is causing damage to the animal. It's not a bad thing as long as you still get the penetration that you need.
If you're not interested in shooting that "far" (cough), you can use the same knowledge to reduce your recoil. Use a lower muzzle energy cartridge with a high BC bullet like the 6.5 Creedmoor with a 143 ELD-X. Believe it or not, at 200 yards it's only down 500 ft lbs compared to the 300 Win Mag 150gr TSX. That's less difference than the 150gr vs 200gr comparison. (At 500y, the Creedmoor has MORE energy than the 150gr 300 WM.)
Long story short: heavy for calibre bullets carry not only more energy but also more velocity at longer distances. And drift MUCH less in the wind. Or lets you shoot a lower velocity, lower recoil cartridge with the same results at the animal.
If I was going to use a Barnes, it would be an LRX, nice and heavy with decent BC. But it still has the disadvantage of less terminal damage and higher velocity threshold for full expansion. Yes, the Barnes is more reliable on tough shots and tough animals; it has its place, I've said that before. No, it's not the be-all, end-all hunting bullet.
