how many shots?
you might want to get that thing on a solid rest and re-zero it, lay down some groups before you try and do any more hunting. you could be getting misses where you should have a solid it.
FWIW. I found the tool bags they sell from home depot with the stiff sides work pretty well as a good rest when shooting prone.. cheap and also carry shootin stuff (mags, ammo, eyes and ears) well.
