I live in Indiana it is a shotgun state. With over twenty years of gun hunting I suggest a rifled barrel and a good sabot slug. I have had great success with Lgihtfield slugs and my brother uses the copper solids. I use a Marlin bolt action and can hold a 3 inch pattern in any weather at 100 yards. I will let you know every gun is a little different on the ammo it shoots best. That being said the all time accuracy record is held with Lightfield being shot from a Tarhunt (custom made) 12 ga shotgun. They put 198 out of 200 rounds in a 3 inch steel pipe at 100 yards. What ever ammunition you choose nothing is better than pratice. Pratice with your sluggun just as you would your high powered rifle.
