So, are you trying to make the case that a 60-grain .223 bullet penetrating 15 inches in a ballistic medium is the same as a .50 caliber 450 grain bullet penetrating 15 inches in the same medium?
Yes,if the 450 grain is unexpanded because the 62 grain Federal Fusion expanded to .54 caliber.If your 450 grain expands,then of course not and remember,that expansion and penetration was at 100 yards not 25.
The case I am trying to make is when using a bullet like the TSX out of the .223 at 3100 fps(factory ammo) it is capable of taking Elk,certainly not my first choice,but like the 243 and 30-30 that it is on par with in penetration on game,certainly enough if the nut behind the wheel does his part.
