You must also always remember:
1.Establish a routine for reloading. It will result in more uniform loads and less chance of error.
2.Some primers are more powerful than others (they produce more gas at a higher temperature). Use only the primers specified herein.
3.Shotshell wads differ in their sealing ability. Use only the load combinations specified herein.
4.If you use cast bullets, their diameter, hardness, lubrication, and crimp will affect the ballistics.
5.The shotshell loads in this booklet are for use with LEAD SHOT ONLY!
6.Use only the brands of powder and components shown in our tables. Do not substitute other types.
7.Discharging firearms in poorly ventilated areas, cleaning firearms, or handling ammunition may result in exposure to lead, a substance known to cause birth defects, reproductive harm, and other serious physical injury. Have adequate ventilation at all times. Wash hands and face thoroughly after handling and before coming in contact with food, chewing materials, and smoking material.
