I shoot each year, most of the time it only takes one shot, just to see if my gun is still holding a zero.
So I guess that we can assume that you can put every singleshot throught the same hole,otherwise a single shot will not tell you if the gun is zeroed.Thatwould bean amazing gun and you musthave great shootingtalent for never practising.
I don't have to waste a whole box of 30 dollar ammo just to see if I can hit a target.
No but unlike you,us mere mortals can't put every shot through the same hole so we have to practise to develop and maintain our shooting skills.Unlike you we have enough respect for the game that we hunt to make the extra effort to ensure that our gun is properly sighted in and to practise regularlyso that our skills are adequate to provide quick clean kills every time.I would rather "waste" that extra ammunition rather than see a wounded animal suffer.
Maybe you should think about your own ethics before telling other people what they do or do not need.Yourusername indicates that you are a student,hopefully you will eventually learn something.
