Howdy folks: Figured that here was as good a place to ask??? Do any of you know the history behind the 410 shotshell and what length shell was first produced and how many shell lengths were there as well as what lengths are presently commercially available for the 410 shotgun. I've got a project in mind and was looking for a shorter length hull/chamber to produce a solid lead slug (with the wadding attached and acting as a directional vane) to easily load a bunch of rounds for plinking and hunting. With only one item to place in the hull, loading will be loads quicker than building up loads with various cork, felt, over-etc. wads. Prime, powder, place slug, and roll crimp, done.
Might end up being a short range deer brush gun in the end, but I have no expectations whatsoever, just killing time in my retirement/disability. All I presently know about are the 2.5 and the 3 inch hulls. 12 gauge on the other hand I've seen in 2.75, 3, and 3.5 inch variations plus another shorter than all hull (not sure the length on this one) made by some company of shotgun ammo to increase magazine capacity only. (kind of what I'm doing on the 410) Any and all help would be appreciated and I love history lessons especially on stuff I know not a thing about as this example illustrates. Smithy.
