.22 hornet

[223AI]

Any chance of explaining the physics of getting 155% more velocity from a bullet of more than 57% of the mass whilst using a powder charge containing ~67% energy than a smokeless loaded .22 hornet with a 35 grain bullet?

No physics, just magic and fairy dust only those that own land can access or understand

I always find muzzle energy a useful comparison, so 20 gr at 4800 fps, 1025 ft lb, with BLACK POWDER, now hornet can be loaded to .222 levels but with heavier bullets and loaded way beyond published data (not recommended). I don't believe a lesser amount of lower energy propellant can push a light projectile north of 1000 ft-lb (without magic of course)
