If your not opposed to a single shot look into the savage field grade over and unders with a rifle on top and shotgun under they come in various combinations and are good rifles I had one in .22 & 410 and with rifled slugs the 410 was a pretty good hunting rifle. Also look into the NEF combos they are a poor mans encore as far as the ability to buy black powder, shotgun, and rifle barrels. New barrels are relitivly cheap as is the original setup. Both are good ideas for a person on a budget and give options of more calibers, and gauges without the buying more guns.
