A firearm and ammunition are a system. Their performance is closely related.
You are responsible for selecting ammunition that meets industry standards and is appropriate for this firearm. Use ONLY commercially manufactured ammunition with internal ballistic pressures which are in strict accordance with the specifications of the Sporting Arms and Ammunition Manufacturers' Institute. NEVER use non-standard, reloaded, or "handloaded" ammunition which has not been subjected to internal ballistic pressure testing.
Ammunition, especially reloaded or handloaded ammunition, may have many manufacturing and quality variables (such as type and amount of gun powder). Any ammunition that is improperly manufactured, even the slightest degree, may fail to fire or may generate excessive internal pressures which can damage or even rupture the firearm, causing personal injury to the shooter or those in the immediate vicinity.
Use only ammunition specifically recommended by Taurus for your firearm. NEVER mix ammunition.
