These days, most center-fire scopes are robust enough for use on a shotgun, especially the target loads you mentioned. You didn't suggest a preference, are you thinking of a conventional optical scope, red dot, or a holographic unit -- how about a laser target designator? Whatever you select, for peace of mind, make sure that wherever you buy it has a liberal return policy.
The big question is, how are you going to mount the scope? If you've followed previous threads, you've noted that saddle mounts are the easiest to install, but are the least accurate. Do you have a barrel with an integral cantilever mount? If not, perhaps a barrel/scope package deal would work for you.
In my area, turkey, pot and fun shoots use conventional trap targets, but fired in an unconventional (non-ATA) manner. Shooters wanting an edge typically look to custom ammo. Boomers with lots of Blue Dot are not uncommon. I've always thought of the fixed target events, especially where the ammo is provided, as more of a test of luck over skill. Of course, there are times when a good patterning super tight choke won't hurt your chances.
