I have not tried 8208 in the .303 yet but it is in the right burning rate range for it, Back in the day before ADI powders the top powders for the .303 were IMR 3031
and IMR 4895; 8208 falls right in between those two I have used a lot of it in the.222 and .308 it is very good and accurate, Grab what you can of it the Distributor
has none on there shelves I bough the last one.
