My experience and knowledge from shooting a 10ga, which I shot quite often. The 10ga goes back to the age old theory of *Bigger is Better*, back in the days when the 10ga was a popular load it was better than a 12ga for reaching out there at long distances and touching what you were shooting at, it also offered you more shot to cover a larger area. With todays technologies you now can do the same with half the size of the gun. You'll hear a lot of hunters say *you owe it to the bird to kill him cleanly*, that is very true. No offence to anyone, but using a 10ga or a 12ga, 3-1/2", today somewhat points towards your lack of abillity to work a turkey in close. but not every bird will work in close, so that day the bird beat you. The larger guns have their place, if you have a limited time to hunt or the area your hunting has thick cover the bigger guns are a better choice, but when that little girl walks by you with her 28ga and a bird over her shoulder it's a bit humbling
. The older guns used to have long barrels 30-32", the belief was a longer barrel shot a tighter and better pattern, but again with todays tecknologies a 28" barrel is considered a long barrel, most of todays guns have a 22-26" barrels and chokes that help you reach out there the same as the longer barrels did.
