Slugs might be worse, since they are 1-2 thousands bigger then a standard shotgun bore so they can engage the rifling. Then they hit that choke........ if a lead slug compresses enough, it seems that the plastic hull should too. Or not.
The problem is, rifled slug barrels taper very, very slightly towards the muzzle; not to the degree a choke does. That, and you're pretty much limited to sabots unless you're a jackass like me and like to lead up your bore.
Conventional foster/brenneke slugs work nicely from a smoothbore, anything tighter than an I/C or Modified will deform the slug upon exit, and you'll lose accuracy (if not stretch the muzzle where the choke tubes screw in).
Now, I definitely see where you're coming from. But asking a shot cup, the contents of it, AND the hull to pass through a choke? Ehhh... really pushing our luck here.
Sometimes you just have to Cowboy Up.
