>is that if you specifically buy their 220/212 bolt action rifled barreled shotguns for slug hunting the mags don't work and you have to use it single shot
It's what I've heard from owners of those sluggers. Also that they like having such big and heavy projectiles but with rifle precision and range.

I think it's owed to the nature of shotgun shells, the slightly squishy plastic hull and the flat nose just is not very good for box magazines. Even in better box magazines, the hull tends to deform under load over time.
