Regarding use of "+P" ammunition in Rossi Firearms.
Many Rossi firearms are "+P Rated" for SAAMI Recognized +P loads. These products say "+P" or "+P rated" in their product descriptions.
These are the only +P Loads recognized by SAAMI:
These are the only pressures, by caliber, that are recognized by SAAMI. Shooting any ammunition in a Rossi firearm above the pressures recognized by SAAMI voids the warranty and places the shooter at great risk for serious personal injury.
