Hunting Deer in NY its illegal to use Buckshot.
Hunting in other states that allow buck, I'd recommend not going with the cheap remchester slugs at Wallyworld and opting for the Federal Flite Control Wads/buckshot loads.
They group tighter than any buck loading I've ever found, and they use copper plated shot (less pellet deformation=better flight profiles=less erratic patterning down range), buffered shot (buffering media helps keep the shot packed tight and aids in keeping the shot from bouncing into one another thus reducing pellet deformation), and the flite control wad holds the shot together well past the muzzle and the flite control wad itself slowly retards once its passed the muzzle and "gently releases" the shot slowly and cleanly.
That said, I'd prefer to use a Slug for Deer. With a slug its either a hit or miss (a hit does not guarantee a good clean kill, its all about shot placement), whereas buck allows the possibility of a one pellet wounding shot; not ethical for game hunting.
I prefer my Buckshot for self defense against 2 legged vermin and for pests such as hogs that are not game animals but invasive species that must be hunted down by any means possible.
