I,m not saying a 22-250 is better than a 416 remington mag because it's faster. I'm saying you cant just chunk a big ol piece of lead out there at a 1000fps and say its gonna be better than a smaller faster bullet.
A 416 rem mag is pushing a 400 gr bullet at 2500 fps second, with 5000 ft lbs of energy, that some serious umph, why ? VEOCITY!
A 45-70 is pushing the same 400 gr bullet at only1300 fps second with only1500 ft lbs of energy, why ? no velocity.
