If your on the prairies, and have the chance for long range hunting, then a rifle is a clear choice. Something like a flat shooting 7mm rem mag is a good choice. If your hunting area offers only 150 yard shots & under, then a shotgun is good, and then you have a gun that you could use for waterfowl hunting also. A rifled barrel shotgun with good sabots, is quite accurate. Then just switch out the barrel to a smoothbore, and hunt waterfowl with shotshell. You can buy shotgun combo's, that come with 2 or 3 different barrels, and if its a remington or mossberg pump, then you will spend less $$ on the combo, over a quality single rifle.
