During our muzzleloader season in Wisconsin, we are only allowed non magnification scopes. So when hunting I use a Nikon 1x20mm, (2) T/C 1x32mm, and (2) Traditions 1x32mm depending on what rifle I decided to use that day. All of them IMO are a lot better for aiming then open sights for me.
When playing at the range I like Nikon, Bushnell, Simmons, and a Traditons depending on what rifle I am shooting that day.
