The BRAS (breathe, relax, aim, squeeze,) technique is the same but every rifle is a little different. Being a military town there ought to be alot of pawn shops there. Go down and handle some and see what best fits your frame. Maybe get in good with the owners and strike a deal. The terrain in Kansas can be different from area to area so try to find something that can make long shots as while short. You want something that you can shoulder (pull up and aim) quickly with one smooth light and quite movement. If you read some of the past post on rifle and shotgun choices it will give you a better outlook on what you may need. I like the 30/30 Marlin for a first timer but the 30.06 and .270 are great all around rifles also.
If you don't understand the technology which you depend on, you will soon be a victim of that technology.
