Perhaps I should clarify my statement as I use 2208 in 308 and 303.. 2209 in 243 and 260.. AP70 in 44/40 38/40 357 45colt 44mag and 32/20 .I use trail boss in a myriad of calibers as well. What I was trying to say is if there is a better powder or more efficient I will usually buy it rather than use what ever is sitting in the cupboard.I use US869 in the 50 cal but would not try to make it work in anything else.
