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.
NO
You can, but, you should not. The frame is not rated for +P
Overall length The 38 special is a stronger cartridge. If you have a .38 Special revolver it can still shoot a .38 S&W but not the other way around.
Yes.
You can shoot them in a .357 Magnum revolver, but that's about it.
It can be done, but, it is not recommended
44 magnum and 44 special.
1. It can, but, it is not advised. 2. It is stated by Smith and Wesson that the model 14-3, which is the third change of the model 14 can safely shoot plus P ammunition.
In a .44 Magnum revolver, yes. In a semi-automatic .44 Magnum (such as the Desert Eagle), no.
Needs to be examined by a gunsmith.
No. .357 Magnum uses more powerful loads and produces much higher pressure than the .38 special. Shooting a round with .357 pressures in a .38 gun is very likely to blow it up. .357 Magnum has a longer case than the .38 Special. This was done specifically to prevent .357 ammunition from being chambered in .38 revolvers. If you can chamber a .357 in a .38 special revolver, have it checked by a competent gunsmith before shooting it.
