.30-06 is a great choice! I have a Howa 1500 in '06 and absolutely love it. I'm assuming this is going to be your first rifle purchase and the '06 is great because it's so versatile. If you want to branch out to hunting other game like hogs, you'll be fine. There's a reason it's one of the most popular hunting calibers. I like using 185gr. since it packs plenty of punch and my gun shoots it the best. Best of luck purchasing your new rifle.
