When it comes to hunting rifles, which do you prefer, a common caliber such as a 30/30, 30-06, 270 or a not so common caliber such as a 325, 204, 260, 280? Just curious as I'm always thinking that if you use a caliber that is common and need a box of rounds, you can usually find those(even though you should never get into a situation like this) as opposed to Johnny's General store not having a box of 280's or 204's. I know some like a particular round and load their own and always have plenty on hand, but tell me which you prefer or use.
