"In the heat of the moment" to mean is when hunting...right?The only way I know or can suggest is practice shooting like you'd be hunting this includes shooting position, rests, angles, different clothing, etc. ie: shooting from a kneeling position using a rock, solid tree limb, or shooting aides(sticks, bipod, etc)uphill at the target. Instead of a bench straight away shot only add some realism to your prep.

Of course fit and set up or your scopes eye relief are mandatory like mentioned previously, however your comments to me meant unexpected touches in the field. Which I assumed meant fit, setup, etc were good. If you crowd a scope it doesn't take big recoil to kiss you, my closest encounter was the first 2506 I owned - prone uphill shot at adeerleft me with a bump but no blood.

Good Luck.
