BTW, the bullet on the far right is "only" doing 2700 fps so apparently did NOT need hypervelocity to function well....
never did I mention hyper velocity, only velocity whether it be from a
30-06 at 2700fps or a 30-30 at 2400fps. or a 45 at 1100fps.
now lets compare the killing power of all three. All three are using the same bullet weight 180 gr., we all agree the 30-06 will have the most killing power followed by the 30-30 then the 45.
Do you see a pattern ? yep velocity. They all use the same bullet weight but the one with the most velocity has the most killing power. even though the .45 has the bigger bullet and frontal area. the speed is what gives the 30-06 the edge.
I'm not saying a 17 rem has killing power because it has speed (4000fps). Its just that the speed of a projectile gives it the killing power. If that same 17 only shot 1900 fps second it wouldnt have near the same killing power it does at 4000 fps. A given projectile will have more killing power the faster it goes.
