IMO the 303 is a good caliber, don't get me wrong. But the 9.3 is a better size if there are big brown fuzzy critters around. It's just under the power of a 375 H&H so it'll work for about anything with good shot placement.
It's also a rimmed shell that is better for DR's.

"When you see that in order to produce, you need to obtain permission from men who produce nothing; when you see that money is flowing to those who deal not in goods, but in favors; you may know that your society is doomed." Ayn Rand
