Altitude effect on point of aim

Wondering if anyone could offer some insight on the effect of altitude on point of aim? Had a trajectory dial made for my 300 WSM based on sea level and 60 degrees F. Was wondering what effect an altitude of 8000' would have on my point of aim?

Going to depend on the load you had the dial made for. Use an online calculator and you'll know.

But looks like an average load at 500yds might be about 3 inches higher at 8000. A full value 10 mph wind will have about 5" less drift at 8000'/500yd.

It would shoot a lot flatter with less drop at 8k compared to sea level. I use the Nightforce calculatorcost a few bucks but very good. Also baro pressure has a lot to do with it.
