I use an open sighted 30-30 for when I am walking through the woods. I usually do not have a shot over 50 yards when walking. It is easier for me to find the deer with the open sight than with the scope. Also I can get a second shot off pretty quick if need be.
That's pretty common out here, you just do what you have to do. Anybody who hunts the wide open country for awhile leaqrns how to hit running critters. But sitting in a foxhole, there's spiders in there isn't there? Spiders scare me
One morning early in the season here, I had to knock a spider off my tree stand platform before I could climb in. I'm not saying it was big...but I heard a distinct thump when it hit the ground 20 feet below.
I was afraid I was going to have to shoot it if it started climbing back up...LOL.
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
