I am currently deployed to Afghanistan so my research ability is limited. Is anyone using the new IMR 8208 XBR in the 6.5 X 47 Lapua with 140 grn bullets. I have a 1/8 twist bull barrel being delivered before I come home on leave in march and need some starting loads. This cartridge has limited info on the internet. Thinking since 8208 works good in the 6MM BR and 6.5MM BR, it should work well in the 6.5 X 47 with the heavier bullets. I also use AA2520 and Varget alot, so if these might be better in this cartridge, what would be a good start load?
