50-300 depending on specifics
It should be marked on the gun- something like .410/ 45 Colt.
Almost certainly NOT an antique. Made by Leinad Inc. in Ducktown, TN. They also made a side by side .410/.45 derringer. I have one and it is very impressive to shoot.
"Best" is a subjective term that means different things to different people. Are you talking about a revolver, semi-auto, single shot, full size, micro, mid, derringer, etc...

Given proper shot placement, none.
45 cal. Long Colt (.45LC) rounds like those used in a 45 cal. revolver. Many of this type of Derringer also can fire .410 gauge shotgun shells. Do a search for your specific model and get the manufacturers recommendations for ammunition.
No such weapon made by S&W
How much is a old black powder only 45 cal long barrel pistol worth?
