28.2grs of XBR 8208 and CCI 450 primers work very well in 3 different 204s I load 35gr Bergers for. It is a max load so approach with caution. I use to load 27.9grs of H4895 but I like how the 8208 meters better. I used BL-C(2) for 40gr Vmaxs and gopher shooting but found POI move way too much when I was out calling coyotes in -35 to -40C weather, might be alright in BC. but MB. winters are just a little harsher.
