Reloder 21 Question?

[Rob Carney]

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

I don't think it will work too well in the WSM case. I had 2 cans of it and it shined in the 257 Roberts. I'll dig up some data.

The Lyman 45th edition has load data for the 30-06 but lists different bullet weights and of course there is no data for the 300 wsm. Suggested starting load for a 130 gr bullet is 50 gr and max is approx. 56 grs for a 168gr bullet. Probably going to need a different powder for the 300 wsm.
