I own 2 savage axis. one is an axis 2-223remHB and the other is so old it was the next year after the edge and its a 223rem pencil barrel. my dilemma is below.

I don't shoot the pencil barrel that much if at all other than occasional coyote hunting cause of the weight. I have been playing with the idea of heavy barreling that one in another caliber like 308, 22-250, 243.

how hard is it to swap barrels?

would it be worth it or just buy another gun?

keep what I have because the farthest I can shoot is 200-300yards max and don't really need another caliber?
