Anyone know if Accurate #7 has changed in the past 10 years? I just used up my 10 year old supply and the new supply looks slightly different.
My Hornady book calls for between 8.5 grains to 11 grains for 10mm auto with a 180 grain bullet. My book is about 15 years old. Should I be referencing a newer book? Can anyone with a new book double check the grains for a 180 grain 10mm bullet using Accurate #7?
