Rather than argue incessantly about number of shots necessary to determine what your rifle will
actually do (precision) and where it will
actually put those shots (accuracy) (which I've done many many times on this web site and really do not wish to yet again get involved in a another protracted argument) suffice it to say that a larger sample size is much better and more reliable than a smaller size. (rules of statistics and probability).
While important on the shooting bench it is also important in the field to know exactly how you, your rifle and ammo will perform and this takes a relatively larger sample size and in the end you will waste less ammo. After determining what your rifle, ammo and you can achieve and completing the zeroing in process then start to practice various shooting positions under realistic hunting scenarios . Happily many shooters are now starting to realize this and much is written about this very subject. You have but only to google it on the web.
Perfect hunting weather scenarios are rare and I only say this to emphasize that one should be very cautious about shooting beyond your means. You might attempt such a shot
if conditions were perfect but more often than not you will and should stalk closer. This is advice directed at the OP which is obviously a hunter new to the sport.
