im serious you fuck
Mossberg is a solid gun. I own a 12 gauge Mossberg 835 ulti-mag. It does what I bought it to do remarkably well (kill turkeys). I've never missed with it, it has never jammed, and it is fun to shoot. Is it the right choice for shooting clays? Absolutely not. I would never recommend it, or any other pump-action shotgun for that. The amount of time it takes to cycle a new round into the chamber means you have to leave your sight-picture, chamber a new round, re-acquire your sight-picture, then get off another shot. With a semi-auto or double-barrel you can stay on target for both shots.
Shooting trap or skeet with a pump-action can be done. It is fun. You're still blasting targets out of the air! It will be frustrating, as you will not be breaking nearly as many birds as the people with whom you are shooting. Your gun will look out of place, and you'll be thinking about upgrading from your very first time out. Spend the extra little bit of money. Don't be afraid to buy used. Also, don't discount a 20 gauge. If you are smaller in build, younger, or simply don't want a bruised shoulder, there is nothing wrong with a 20 gauge. Target rounds will not kick like a hunting round or slug, but after a few hundred shots you will feel it.
