The standard ancient wisdom is to shoot slugs from a cylinder bore, for best accuracy. My experience is that each gun & ammo combination is an individual, and while many follow the same patterns some don't.
If your modified or full choke gun shoots well with slugs, then it does, where an identical gun might not.
Forster type "rifled" slugs can SAFELY be fired through any choke. The "rifling" on the slugs (actually fins, having nothing to do with spin) are there to allow the slug to compress and safely pass through chokes.
Some choked guns are more accurate with them than others. Some are accurate with brand/load A and not with B, etc.
You just have to shoot some, and see.
