That is a very nice buck. Can you tell us more about your shotgun? Is that a Mossberg?
Priyan wrote:Eh, they are OK on shotgun meant to fire slugs but still its like a tactical muzzleloading rifle with 3 point tactical sling together with red dot sight and cleaned with high silicon teflon infused oil. Some states allow only shotgun for deer hunting so some p[people prefer slugs but still the effective range is about 100 yards. Well, if you need scope to shoot 5" group at 100 yards you should not be shooting.
Priyan, you shouldn't believe everything you read on ARF.com.
Many states in the US do not allow deer hunting in certain areas unless you use a shotgun. Most hunters use slugs as you usually end up with a .50 caliber (or so) projectile that you can shoot with reasonable accuracy to a distance of 75 or 100 yards. There are slugs guns available now that can shoot accurately up to 150 yards and more. Many people who shoot these slugs use slug barrels. Some of these have rifle sights (with a large bead to aid visibility). Some just have a bead. There are slug guns available now that will shoot two inch groups at 100 yards which is as good as some hunting rifles. However, your average pump shotgun, shooting slugs with a smoothbore barrel and using the bead on the barrel, will be hard pressed to give you a five inch group at 100 yards. I'd say the average is going to be closer to a two foot group.
There are two main reasons people use optical sights, one is that as you get older, you lose the ability to use the rifle sights to their maximum effectiveness and the other is that with magnification, you can place your shot where you want to. It is much easier with a scope or red-dot. Whereas, often at the extreme end of their effective range, the bead on the iron sights covers too much of the deer to accurately place your shot. If you care about shot placement and bringing your deer down humanely, you should do everything possible to do so.
Also accuracy doesn't matter that much while shooting buckshots.
Shotgun scopes are for guys like gecko45.
Actually you're quite incorrect Priyan. Not many people use buckshot when shooting deer. I, personally,don't know anyone who uses buckshot for deer hunting. Buckshot spreads out too much unless and you are really close, you have a good chance of missing your quarry.
I often hear people denigrating night sights or an illuminated reticle. For those who actually go out in the woods and hunt, there are many times as the sun rises (or sets) where you can clearly see your quarry but not the bead on your iron sights. These are the times when an illuminated sight is handy. Ethical hunters who cannot see their sights clearly, will pass on the shot rather than risk wounding the deer. This can mean coming home empty handed. When people make ignorant comments like that, if you ask them if they hunt, quite often the answer will be "no".
Gecko45 types don't hunt. Hunting very rarely provides instant gratification.
To answer the OP's question, unless you are hunting with slugs, you do not need a scope. For home defense, as haji mentions, you do not need a scope.
