Thread: Reloder 21 Question?

  1. #1

    Reloder 21 Question?

    I recently inherited a few Lbs. of Reloder 21 powder in sealed, undamaged square cans. It appears that Reloder 21 was discontinued in or about 1972; so, I've not been able to get decent loading or burn rate information on it. I'm planning to shoot .30-06 Springfield -- 140 to 170 Gr. and 300-WSM -- 140 to 180 Gr bullets with it. A response from any old-timers out there with a good load-data memory or decent older reference books would be appreciated. Thanks, Rob Carney
