Jarvis Power Loads are precision-engineered cartridges designed for use with Jarvis Power Actuated Stunners (PAS). Available in .22R (5.6mm R) caliber, they are ideal for stunning small to medium-sized livestock, including poultry, sheep, pigs, and cattle. With grain strengths ranging from 1.00 to 4.00 grains, these cartridges provide the appropriate force for humane and effective stunning. Lower grain loads are suited for lighter animals, while higher grain loads—such as the red (4.00 grains)—deliver the necessary power for larger livestock.
 
Safety is a top priority with Jarvis Power Loads, ensuring controlled and reliable performance in professional meat processing environments. Each cartridge is precision-engineered to meet industry safety standards, minimizing the risk of misfires or inconsistent stunning. Operators must always select the appropriate grain strength based on livestock size and follow all manufacturer specifications for compatible PAS stunners.
 
Proper handling and storage are essential—power loads should be kept in a dry, secure environment, away from moisture and unauthorized access. During operation, personnel must wear appropriate hearing and eye protection, follow safe loading and unloading procedures, and ensure the stunner and cartridges are in proper working condition before use. By adhering to these guidelines, Jarvis Power Loads provide a safe, efficient, and humane stunning solution for livestock processing.
