If your question is in regard to the Smith and Wesson Model 36 revolver, these were made in caliber .38 Special and that IS the ammunition to use in one. The 36-1 is an early model, and may not be suited to the use of +P or +P+ .38 Special ammunition, which is loaded to higher energy levels than standard ammunition. If you are seeking info on use of +P ammo in a specific S&W revolver, you should contact customer service for Smith & Wesson.
As long as both the rifle and the revolver are chambered in .44 magnum you can use the same ammunition for both. I have a Henry rifle in .44 mag and a Ruger redhawk .44 mag and I use the same ammo for both. That's one of the nice things about that caliber.
Depends on how old the revolver is.
