I feel a .243 is a better choice.
I agree, the 243 is a better choice for big game and the minimum here in Wyoming......
Back a few years on a Wyo lope hunt I happened into the G Warden a couple times. Asked him what he liked to use, he had a couple rifles. But, preferred the Swift to all as he felt it ended things quicker than the other big rifles...grin
