Hogwash! I know guys that get their plane every year with .243s and 7-08s. I was on a cull hunt where we took down 67 Piper Cubs and nobody had anything larger than a .338 WM with a majority of those being .270s.
I'm sure some stunt shooter is going to chime in with how he killed a deHaviland Beaver with his .233 as well.
It all comes back to the age old argument between caliber/velocity and bullet placement. I believe bullet placement wins every time.
But I will add that a 300 Weatherby is the ONLY rational choice for shooting elk.
