I grew up in south of you in the Great Lake State. For hunting deer, a shotgun was the only allowed firearm (below M66 or something like that?). It is a very effective tool for clean, safe, and humane harvesting of whitetails.
The new guns and ammo are leaps and bounds over what we almost 30 years ago. Far more accurate at much more 'huntable' ranges. Grab some ammo samples and test that barrel. Don't be afraid to shoot it out to 100 yards.
