I think all adi powders are single base powders and cfe223 is a double base powder so is temp sensitive, I stopped using cfe223 as in the summer it gave me ejector swipes.
BM 8208 is good up to 123gn bullets but be careful going past 123gn as it spikes very quickly.
I use ar2207 on the 84-90 gn projectiles and bm8208 after that.
