I have a Rossi .44 mag lever gun that I want to deer hunt with. Question for the experts....Should I use a scope, red dot or stick with the iron sights. I'm thinking that around 100 yards will be the max I would shoot this rifle out to. What are the benefits and drawbacks of the different set ups? I searched around for suggestions but didn't have much luck getting answers. Also what is the ammo of choice for others using this gun for deer hunting?
