great advice there from above,,
I have been hunting many years and when I practice I am a pretty good shot,,
but as said ,, the deer can move so you need to get close, ,ohhhh yes there are those that have killed the deer long range, but that is just not a high percentage shot,,
I hunted last year in texas and had deer at 25 and 30 yards,,, I have seen them get out of the way at that range to many times,, I just watched and knew I would get a good close 10 yard shot,,
well it didnt happen,, I would have stretched to 15,, but that did not happen either,,, sooo,
I will try again this year,, I feel lucky,,,,
and i am not saying that you should not shoot over 15 yards, I am just saying that past that things may not be in your control,,, no matter how good the shot is,,,
