I always use slugs for my first few shots.I figure he is down or running at this point.At least you have a chance of putting a little somthing more in him while he's bounding off.I hit 7-10 pellets at a 3D deer target at 80yrds with a improved cylinder smooth slug choke/compensator.With a browning A5.I know they are small pellets,but anthing helps to make that blood trail a little bigger.Has anyone shot deer with #4 buckshot with good results?There are 27 pellets in a 12ga 2 3/4 round.Pretty much like bird shot effect.Im sure up close that deer would be blow off his feet,.Im just looikng for a little extra damage after my first shot.They are TOUGH animals!!
