I travel the fields a lot during rifle season, I see no difference in POI from my shooting bench with bipods to the hood of my truck, providing that I look at my level and make sure the rifle isn't canted and I put my weight against the truck. Have you shoot it at all since say it was 65 degrees and now its 40 degrees, depending on powder, that could make a big difference, with some powders I have seen 100fps+ velocity drop with a 25 degree temperature drop, ball powders are typically the worst. I took a doe Thanksgiving day with my 300wby off the hood at 441 with no rear bag, I think you need to do a little shooting and see what's happening.
Just ran 3 diff bullets through the computer. Changed the velocity by 100 FPS on all three. The difference in POI is around 2 1/2 inches at 400 yards.
That is not the problem if he is able to shoot as good as he says out past that. Plus the fact that it would take a pretty dramatic change in temp to change things by 100 fps with ANY powder.
