Using a 6.5 Grendel Pistol in MN Deer Shotgun Zone

[dpete]

What do the MN regs say? Any interaction with a warden who isn't clear on the law might be arrest first/find out about law later. He'd more than likely see an AR pistol as a rifle in a shotgun zone. A proper bullet out of a short Grendel is just as deadly if used at nominal hunting ranges.
