Yes, but, this thread is not about "all types of deer and elk." It's about whitetails. As for your "all around gun opinion", I would venture to guess that the .30-06, the .308, the 7mm Rem Mag, and any of the various .300 Mags would fill that bill quite nicely.
Really,, wow a 300 mag is needed for deer . I really think you didn't read entirely what I wrote and you enjoy arguing if so go for it.
