What was the original length of the .410?
I have a Ranger sxs, made by savage, sold by sears that dosn't like the 2 1/2 inch shell. The gun only has .410, ranger, and patented 1911? stamped on the gun. The fired shell sticks in the chamber and there is a taper to the end of the empty hull.
This gun is from my youth, and we would buy any .410 shell on the store shelf. The 3" shells didn't fit so very good. So over the knee whent the gun with just the right pressure(about as hard as i could pull) the action would lock shut. seemed the gun would kick like a 12ga.
