Some say the tools do not make the craftsman, but we say that one should learn to use one's tools to one's ultimate advantage. Here follow some pointers to make the best of your rifle.
Assuming you are using optics on your rifle, take the time to teach yourself the basics of your optical system - the more you understand the intricacies of it, the better you'll master the results of your shooting. No matter how fast and strongly it leaves your rifle's barrel, a bullet is an object with a mass and surface, therefore affected by the pull of gravity and the flow of the wind. The further you are from the target, the more relevant those forces become, and the only way to establish a useful cause-and-effect relationship between those variables is by a sequence of trial, error and adjustments dialled into the scope.
The more you know about how physics affect the complex interaction between all variables - you, your rifle, your bullets, all the way to the final results, the better the final results. Then move onto the details of the shape, weight, type of gunpowder, terminal velocity, deviations, of bullets, Then learn more about different types of barrels, and how their interior surfaces affect these complex interactions of forces .
The way you position yourself and your rifle, the way you anchor the front of the rifle on a bipod or the center of the rifle on a tripo or a stand, the way you use your forearm our a rear bag as a support, all will affect the initial accuracy of your shot and the consistency of your shooting. Take a minute to consider these.
