if i were you, go watch youtube videos on people who buy them, shoot them and rate them. there is a good article as well comparing the mossberg patriot, savage and the remington 783. if youre considering one, consider those other 2 brands as well. after you've done a bit of that research, go into your local store and put your hands on it to see if you like it.
if youre going to be hunting, 308 would be a good round because it is quite cheap, you can buy lots of bulk ammo for target practice, and then get a real nice hunting round for when youre in the bush.
for what its worth, i dont own any of those guns. but will be likely buying a remington 783 in 308. from what i have read the patriot is a bit more money but i have seen or read more negative reviews relating to quality control issues on the patriot than the other 2.
