Richard Mann,one of the NRA's contracted experts, helped develop the Bullet Test tube. (It�s slightly harder material than the gelatin used in Federal�s test.) Mann tested Federal�s loads in it and on deer, and here�s what he found:
When robustly constructed bullets like the Barnes TSX, Nosler Partition and Fusion are used inside 150 yards, penetration with the .223 Remington is on par with cartridges like the .243 and the .30-30 Winchester.�
We all know the 30-30 Winchester has killed a boat load of Elk and most other game and when the .223 penetrates equally with a well constructed bullet,within it's range and a well placed shot,I see no problem using it on Elk,just like the famed .243.
