I see it’s been stated elsewhere in this thread as to the effective use of SA 6.5mm, 7mm and 7.62mm. I for one subscribe as to not needing magnum cartridges for the game listed. If the SA is not your thing, and I know it sounds rather boring, but the 30-06 with today’s bullet technology will easily dispatch at very long range all critters big and small. 130, 150, 165, 180, 200, 212, and 220 grain bullets offer quite the selection for whatever your needs may be using the 30-06. Velocities will range between 3,350 fps down to 2,400 fps from those bullet weights. Hard to find that kind of versatility in a standard cartridge with 1-10 twist and its about 120 years old, so it’s well proven.
