I use a 200 yard zero for my scoped bolt action center fire rifles. We use the 30-06 and the .338 Win. Mag. At 100 yards the group centers about 1.5 to 2" high, dead on at 200 yards, about 5" low at 300 yards and close to 2 feet low at 400 yards. Our reason is we do not do much shooting at big game past 200 yards and I want the bullet to land as close as possible to where the cross hairs are placed. I know all about the "maximum point blank" range theory for a given load. I still prefer to zero a rifle for the distance the majority of our shots are taken. This is the zero I want for hunting big game in Alaska with a scoped center fire rifle. At what range do you zero your scoped center fire rifle when hunting big game in Alaska?
