I have gotten to the point, after many years of buying and trading guns, then kicking myself many times for getting rid of certain ones that all the guns I currently own, which is not a large number by any means, are liked equally!
I don't have many guns, but the ones I do have, there really are no favorites! They each serve a different function and they each have pros and cons (mostly pros). I also equally enjoy shooting any and all of them! I reload for all of them (except .22 and shotgun).
Also, I feel that there are no guns that I need to have.
I have enough assortment that I can hunt anything in the world (my 500 Magnum is advertized that it will kill anything on the planet).
