I've seen so many folks shooting a movable single pin sight over the last few years and honestly, its been a thing I have questions on, especially the folks who have shot them for a while and have lots of real world experience in the woods with one. I'm a fixed pin guy, but with my eyesight aging (thanks technology), wouldn't mind cleaning up the clutter a bit. But, I'm struggling to see what other advantages there are and have some real concerns. So, please entertain me a bit if you will. Other than a cleaner sight picture, what are the other advantages? How do you shoot with one? Do you adjust for every deer from 20 to 30 etc? Has it ever cost you an animal because you didn't adjust it? I'm more curious as to why in the world I'd want to have to worry about adjusting a sight when taking a shot at an animal. Please entertain me.
