RE: Ithica Deer slayer
Deerslayers have always been fine slug guns. Fitted with a rifled barrel and adequate sight it should serve well to 100/125 yards I would think. But it's not the gun that makes the shooter, it's the foundation the shooter brings to the plate that lives up to the gun.
You might want to think about posting stuff like this in the GUNS or FIREARM REVIEW FORUM.
