You might want to consider experimenting with zeroes, if using the post & crosshair reticle on some scopes.
At first, I zeroed using the top of the post, which was a tad above the crosshair - but found that I was shooting high when I was excited, as in during jumping a bedded deer.
I think the thinner post tip was "disappearing" to my view, in my excitement.
So, I eventually switched to a zero at the junction of the post & crosshair, to allow for my idiosyncrasy.
YMMV, of course.
