Well your statement of wanting to shoot long distance... I would look at the Knight Mountaineer, T/C Triumph, or CVA Accura. Depending on what you hunt, if you hunt elk then go 50 caliber. If its only deer and say hog.. then a .45 caliber would be fine.

I would avoid the kits. Instead get a good rifle, a quality scope, and then the accessories on the side as you find you need them.
