[QUOTE="porkchop401, post: 718084, member: 29195"] Fellas , my home address is at around 200 feet above sea level in louisiana where I worked up the hunting load for a elk hunting trip in Colorado where elevation was adout 9500'. Accuracy was averaging 3/4" @ 100yds. After rangeing testing the load out to 600 yards and adjusting the numbers for altitude and average temperature range I felt I was ready to go !! . After arriving for the hunt I went to the local dump/ shooting range where I shot a group that measured a little over an inch , so I shot another and it was just about and inch. After checking every thing I could not find a thing loose . After returning home I check the zero and after a cleaning the rifle shoots at its previous 3/4" grouping . The rifle was clean when shot in Colorado. I shot both sets of groups from my portable bench whitch I took with me . I am at a lose here , Is it possible for a load to be affected in terms of acccuracy aside from trajectory due to altitude and or temperature? thanks PC401 [/QUOTE]
