What difference does it make, if no club says one can't shoot SC with their field shotgun. Seems to be a personal choice.
That is only an observation. Of course you can shoot anything you want, it just isn't what it originally started out to be as a shooting discipline. If you shoot most any clays range today, you will have guys screwing chokes in and out, long ported barrels and adjustable stocks. Those guns were designed to meet changing conditions on the current clays range.
I still shoot SC on a regular basis and am one of a few that shoot field guns. Most are shooting Sporting Clays guns.
Sounds like you're talking about Trap guns.
If a shotgun fits, it fits. With Sporting guns, most are fitted to pattern 50/50 or just slightly higher like any field gun, and precisely why this is the fact is because of the presentations mimicking game. Rising, Dropping, Crossing, Quartering
Some guys around here win National and World events with "field guns" right off the rack
