Brent I have wondered the same thing. I think it is because of the gunpowder - black or nitro. As you know you can now load 12 gauge from 3/4oz loads up through 2 oz I suppose, all at less than 1250 fps, but certainly you would have to change powder as you changed the shot weight. I think that 120 years ago when it was desired to shoot a 3/4 oz. shot load (2-1/2" 20 gauge) the available powders would not burn in such a way that is could be done in 12 gauge.

That is speculation on my part but I did read that when the early English 2" shells came out they had considerable trouble making the shells work consistenly because the powder wasn't compatible with the inertia of such a short shot column.


Mike,

All we can do is speculate. I think some other contributing factors were makers looking for a market niche. It also seems to have to do with rivarly between various national interests.

Part of the growth of the .410 has to due with the slow movement to lengthen the case, allowing a greater payload.
