I'm moving to Iowa in December and high-power rifles are not allowed for deer. I have a choice of pistol, muzzleloader, shotgun, or bow. I lived there for a few years and went deer hunting once, with a muzzleloader. But, the season was only a week long, and bucks only. Plus, it's early in the year (middle of October) so the corn is still standing, providing ideal cover for the deer during the day. So, I was wanting to try using a shotgun. How much range and accuracy can I expect out of a 26" barreled 870 using slugs and a smooth-bore barrel? I saw a bolt-action Mossberg shotgun with a rifled barrel at Wal-Mart out there for $275. Is the increased accuracy and range worth it?
