Before heading out on your deer hunt with whitetail outfitters, it is of course necessary to pick a suitable hunting rifle. Let us keep the following points in mind before making your rifle purchase and also elaborate on them. 
Type of rifle: There are many types of hunting rifle like lever-action, bolt-action etc. Also there are many caliber types too. You'll want a caliber that has enough knock down power, but also won't tear your deer apart and ruin the chance at harvesting the meat.
Type of location: Location also matters for choosing a rifle like if you are hunting through thicker passages like bushes, faster-loading gun would be appropriate to cover the tight spaces. Likewise, to cover longer distance you may need a bolt-action rifle, although they are harder to work in close quarters. It is said that the noise from loading a bolt-action may leave a chance for the prey to escape if you are close enough for the prey to hear you. 
Type of Prey: The type of prey you want to hunt also should be kept in mind before choosing a rifle. To hunt smaller animals, you may need a rifle that can hold a good pace. Many recommend going hunting with smaller semi-automatic rifles for hunting smaller animals. But a lever-action, bolt-action, etc is the preferred choice for hunting larger game.
After determining these conditions, it’s time for you to choose a rifle. Though there are many brand names, it is always better to go with the one with which you are most comfortable with and could be the most user friendly to your needs. Proper care, storing, and maintenance of the rifle would also give it a good chance of lasting long enough that you can pass it down to your children. 
After choosing which one to buy and after getting a good rifle, you will need to learn your gun well. Read the manual and know the ins and outs of the gun. Know how to keep it safe and secure, which is the utter most important thing with all firearms. Keep it locked up when you are not using it and please make sure it is out of reach of teenagers, children, or young adults who may otherwise find it.
