A .410 slug is 80 grains. That is like trying to kill a deer with a .380 pocket pistol. I know it has been done but there are better ways to do it.
I have lived near the Amish and do not adhere to their hunting methods. Most feel they sould be exempt from the game laws and hold themselves above those laws as they do many others.
Go with the 20ga/.22 rossi package. they even offer their 20ga as a slug gun.

At the least I would buy the 20 package and cut the barrel to 18-19 inches and mount some of the magnetic or stick on sights now available on it. Midway has 11 pages of sight choices.
It would only weigh a few ounces more than the .410 trube and give you three times the gun, and a proven deer killer.
The small game shells are cheaper too and you have a better choice in slug loads.
