Hi everyone, I am hoping that someone, anyone can help me out. My father in law, who has no use for computers, needs info for his new rifle. He is getting a 1 in 10 twist barrel that is chambered for a 6x47 Lapua shell. I guess this is a newer barrel, because he is having a hard time finding out info on loads for this. He is going to use 55 - 105 grain bullets. Dose anybody have any info about powder weight, for bullet size. I would appreciate any help that I can get, I'd like to stay on his good side for awhile longer.
