Thanks for the comments, gents. I appreciate it.
From what I am gathering, it looks like the 338-06 is the way to go as I would probably be wanting to use at least 225 grain bullets for my chosen application.
Well...
The .338/210 gr. NP is supposed to punch well above its weight.
But w/ a 20" Bbl., you will probably be lookin' at ~ 2400 fps at the muzzle, and an effective range of ~ 300 yards (1800 fps).
... and a trajectory like a 30-30.
A 24" Bbl would add 50 yds and flatten things a bit.
A .338-06 would add a 100 yds to the short Bbl. and flatten things considerably.
A 24" .338-06 would shoot ~ like a Factory .30-06/180 gr., albeit more recoil.
