Being confident in your rifle and your ability to shoot it is a great part of your success, no doubt. I can shoot to 300 yards and I admit it's fun to be able to hit one that far on occasion. I did shoot a doe at 275 this year and it was fun.
But what did I accomplish?

Shooting far just proves you're a good shot! Shooting them up close means you're a good hunter, particularly if it's a mature buck!
