My cousin reloads for .410. He uses 9.3x74 brass trimmed appropriately instead of plastic hulls. I don't have a lot of detail around his antics, but every time he sees me, he does apologize for ruining/consuming hard to find expensive brass for making shot shells.

MEC is the only manufacturer of shot shell presses that we see around these parts. Not too many folk reload shells anymore because the cost of factory 12 gauge shells come in at similar price points to reloaded shells. Some do reload for harder to find pricey sub gauges such as 16 or 28 gauge, but it comes down to how much volume one shoots. Around here, .410 is a very popular grouse gauge but other than my cousin, I've never met anyone else that actually reloads it. Volume shooting really drives the economics of reloading, typically the hallmark of 12 gauge for clays or waterfowl shooting.
