Rex Powder

The Rex data on this page was developed in the HP White Laboratories (H.P. White Laboratories * 314 Scarboro Rd. * Street, MD 21154) under controlled conditions. No data shown in the ensuing lead data section should be used with steel or Bismuth shot. NEVER substitute components when loading shotshells using this data. Substitution of different components could cause excessive or dangerous pressures, which could damage or destroy your firearm or cause serious person injury or even death to the user and/or bystanders.

Graf & Sons, Inc. has no control over variations in components, reloading tools or reloader's procedures. The individual is soley responsible for any changes in ballistics that may occur using this data.

After choosing an appropriate load, be sure to weigh actual charges thrown by the bushing or charge bar. No bushing or charge bar throws the exact charge as listed in the tables. Such changes occure because of small tolerances in the bushing sizes, tolerances in bulk, density of powder and the way each loader is mounted and operated. It is important to verify these weights for safety and to insure getting the type load you want.
