Does your shotgun have open sites or just the bead on the end?
What is an "open site"? edit: I have a Benelli, see this pic:
https://www.benelliusa.com/shotguns/nova-tactical-pump-action-shotguns?eid=147I hesitate to do target practice at the range because I have tinnitus, and have read in message boards that even with the best ear plugs, some guys permanently worsen their T after practice shooting, which if very bad can be a major drag. When I bought this gun, I did practice shooting it wearing ear plugs and ear muffs, shooting maybe 20 times total, but my ringing got much louder for about 2 months after that day. Thank God it went back down to previous levels. So far mine is pretty mild most days and I barely think about it, but I know guys whose T was mild but later exposing themselves unnecessarily to repetitive, loud nose, now have very loud T 24/7. Not worth the risk. Unless there's a solution I'm not aware of. I do have a deer rifle on my wish list for next year, which is more accurate.
Another thing too, if you get talking to any game wardens they will tell you that a fair amount of deer get shot but left in the woods. I have seen deer shot through the lungs that took off like a bat. You wouldn`t even think they were hit. Sometimes no traces of blood can be found. If you think you hit it just keep looking a little longer, you might get a surprise.
Funny you mention the game warden, one walked across the field yesterday to make sure I had my hunting licenses, seeing me from a distance wearing the hunter orange.
It didn't seem like I hit the deer, but I might have. The problem is it jumped across a fence onto private land. And I'm glad I didn't trespass to follow it (I thought about it) because later I picked out a hunter in a deer stand on that private land on the far side of their field. No tellin' how that Good ole Boy might have reacted. They've got "No Hunting" and "No Trespassing" signs plastered along the fence bordering the Wildlife Management Area. But I did scan the field for 5 minutes and saw no sign of a downed deer. Binoculars would help, and maybe getting permission before hand to go on their land if necessary.
