I have one rifle per purpose.
and I can come up with LOTS of specific purposes. like a turkey rifle, fox, squirrel, fox squirrel..... I have more purposes than rifles really.

in all seriousness I do have 1 rifle that I do my big game hunting with. ruger .243 I've had since I was 16. I call it the death ray
