I have a H&R 12 gauge single and when teamed up with a23/4 in. Brenneke Rottweil rifled slug its a deadly combination and I killed my first deer with a H&R 20 Gauge single with a rifled slugat about 50 yards, blew the top of his heart out, your accuracy is going to depend on the slug and your eyes, they are very affordable try one out. what gauge are you looking at?
