I personally prefer Lightfield EXP in 2-3/4. It is accurate and really knocks them down. One deer I shot from a stand was dead before it hit the ground. The slug entered just to the right of the spine in the shoulder area (deer was facing me with a low head/neck). When I field dressed the deer, the lungs and diaphram were gone - they had exploded. When the season is over, see if any of the gun shops have clearance sales on the remaining ammo. Buy a few brands/types and see how they work in your gun. This will help get you prepared for next season.
