When you initially get into any hobby, a majority of the people get a not too expensive version of whatever equipment is needed for the activity so that they would be able to try it out. Then as they become more skilled and want to attempt new aspects of it, or they learn what doesn’t and does work, they end up getting something better. If you are into pellet guns and you are on the lookout for the best air rifle you can afford, there are a lot of things that you are going to want to search for to be sure that your investment is actually worth it and would make you truly satisfied for a very long time to come.
What is the point? Do you plan to just do target practice? Why do you want this gun? If so, you are going to like to see how far away from you your targets can be, your frequency of target practice and for how long, where you plan on shooting, what you want your targets to be.
For instance, if you would like to spend hours plinking at targets, going through a lot of rounds, you may not like something that is going to need you to pump it by hand very much or you would find yourself getting exhausted very swiftly. If you are hunting, it could be worth 70 or 80 pumps for 20 very powerful shots since you would not be shooting all that much, however, if you are only doing target practice, part of the point is to be shooting very much since you won’t be spending the most of your time walking.
A PCP gun may be the best air rifle option for something like that since you would be stationary and not need to take scuba tanks with you to recharge the gun.
