Sorta funny, everyone talking about energy and fps.
Hunting for meat took place for hundreds of years with nothing better than black powder and lead-lots of smoke, recoil, and veeeerrrryyyy slooowwww projectiles, but these were used, pretty commonly, and pretty effectively at ranges cited here.
If I recall correctly, most of the hoopla about the 30WCF was its flat trajectory-which, if compared to black n lead, was flat indeed. Pundits of the day were saying it was effective well past 200 yards.
Now, it may be possible that in a little over 100 years, Elk have begun donning kevlar, and can only be killed with super bullets and super velocity found in cutting edge bolt gun cartridges...then again, its also possible the Martians have landed.
The great thing about the 30WCF is that while a good bullet sure helps, its not the final word. Light weight, light recoil, power to drop game well beyond paper ballistics. These are why the 30WCF, and the carbines chambered for it, will always be popular.
Good luck, n good shootin.
