The Smith and Wesson model 28 -2 is a .357 caliber 6 shot N frame revolver.
The best cartridges depend on your purpose: target shooting, hunting or self defense, etc. This is a complex area and is subject to debate and opinion.
Thye smith&wesson model 28-2 was chambered for the .357 magnum cartridge.I would say Start with the one round that you and the gun shoot best.Then you can experiment on different weight bullet loads.You may also shoot standard .38 special loads in your model 28.
The best that I can do is say that the smith and wesson model 28-2 was made by smith and wesson from 1961-1969.
