Would you say a sie by side 16" 12 ga coach shotgun is appropriate for fun/cowboy/non-competitive trap shooting?
It's been a year since I started this thread and have since been shooting trap regularly. I'm usually at the trap range on Sundays, and have seen all kinds of shotguns being used.
Although your coach gun was not designed for shooting trap, you can definitely bring it out and use it.
Keep in mind, you'll need to use target loads. Typically 1-1/8 oz of #8 or #7-1/2 lead shot, going about 1100-1200 fps. Shot larger than 7-1/2 is not allowed.
If you want to lessen the recoil, try using lighter 1 oz loads.
Trap range is open on Sundays 0900-1600. Cost to shoot is $7.00 for a round of trap (25 birds) for non-members.
Sundays can get pretty busy so it's better to come early if you don't want to sit around and wait to shoot.
Trap range also opens on the first Saturday of every month. Let me know when you're coming out and I'll help you get started.
You'll have a lot of fun so bring more ammo than you think you'll need!
