I'm planning to take my Krieghoff Classic double in 375 H&H on a plainsgame hunt this summer. It is regulated at about 100 yds. I am concerned about longer shots with it. Compensating for drop is not a problem, what concerns me it horizontal drift. Does anyone have any idea how much the bullit will move laterally at 200 or 250 yds? I know that each rifle and load is different, I'm just looking for a rough estimate. I am looking for a range longer than 100 yds so that I can test it myself.
