What are the must-have calibers these days to keep you covered without tons of overlap? I have friends that would tell me I need a gun in every caliber "just incase". I have friends that would tell me a 22LR will do every job. I obviously fall in between. My calibers that include multiple ways to project them include 9MM, 22LR, 223/556 and 12G. I still feel like I want 45 sometimes but 9MM is fine. I don't hunt regularly but a 270 seems to do the job for me. I can see 308 replacing 270 though. The 6.5 CM looks like it might stick around a while and that will probably be my rifle choice when/if I make it. What about you guys?
