I've only been doing it ten, and I think common sense had me knowing better right after I started!well thanks for the comments. i am a very experienced reloader, have been reloading for 50+ years. i did not buy the powder but was wondering about it. i thought it would be good for reduced rifle loads. but 4759 is the powder i can find in some older loading manuals so now i know. ????stupid questions???????????? if you don't ask you remain in the dark.
