… okay. I’m going to break this down for you.
In my family, there are three shooters. We shoot small clay discs, thrown through the air. Trap, Skeet, and Sporting Clay are the varieties of sport. We use shotguns. You may be familiar with the classic arcade game, ‘Duck Hunt’. That’s the same sort of thing.
My dad is left handed. I am right handed. My mom is small.
My dad’s shotgun is customized to fit into a left shoulder, and has a distinct kink to the butt to fit to the left. Mine is the same for the right. My mom’s is customized to the right, and a 20 gauge instead of a 12 gauge. (it’s smaller.) We can not share the same guns, therefore.
For Trap, which involves a single disc flying in a unpredictable motion, you want a single barrel shotgun, preferably break action (literally, the action breaks open and you put a shell in.) which can only fire one shot before reloading. Further, you want a long barrel for maximum speed and distance. My 36" barrel is a bit extreme, but it keeps a smooth swing.
For Skeet, which involves shooting two discs in a predictable pattern, both launched at once, you want a double barrel, over/under break shotgun, with a slightly shorter barrel. A 32" or so. Clearly, the Trap gun can not be used for Skeet. The Skeet gun can be used for Trap, but not optimally, the added weight is a factor. (We are talking about several pounds of metal here. Not so bad with a predictable swing, not so good with an unpredictable one.)
For Sporting Clays, you have unpredictable speed, disc size, and angle, two at once. Very advanced shooting. For that, you want a much shorter barrel, because the distance is less, and you need the speed of motion and the spread of the shot. A 26" barrel will do nicely, in double action break, or even automatic. You could use a pump for Trap or Skeet… but not for Sporting Clays, generally.
So that’s nine different shotguns, for a simple round of variant sports in one chosen field of shooting.
Plus my Mossberg pump they keep under the bed. (I don’t think it’s the world’s best idea, but it’s useless for sport, (the shells fly out of it when you pump, which makes it rude to use at the club))
Note that none of the sporting guns I’ve described are really any good for self defense. For that, I’d want a pump or automatic, in 12 gauge, loaded with double ought.
It’s a lot like golf, here. Proper club for the proper situation.
(I don’t shoot squirrels. I have shot nutria, which were eating the ducks in the pond at night. For that? Air rifle, scope. All you need. Kills the varmit, keeps the neighbors from being upset.)
