From the threads we've seen on here, I think the RAR will work fine for your use.
As for caliber, coming from someone with quite a few hogs under his belt (but not as many as hogdogs
), either will work fine. I grew up hunting hogs with a .308 and have used a 30-06 as well.
I also would not get too wrapped around the axel on bullet selection. For many years, all I used was 150 grain Remington Core Lokts, the bargain basement of bullets. I never had one get back up, and my largest was ~250 lbs. I've also shot them with Winchester Silvertip which is a polymer-tipped bullet. Good results. I'm certain anything you choose short of a varmint bullet, FMJ, or target bullet will work just fine.
