Saw a similar post (what's your next rifle) and had to post this. Thought it would be a good conversation topic. I said cartridge(s) because I know we all have a select few we can't choose between. Mine would have to be the 30-06 spring. The 257 Robts and the 222 rem. I have an odd bond with the 06 its rich history and how versatile it is. The 257 again a rich unique history and such an all around number. The 222 is so accurate and so often over looked. 3 very fine very useful cartridges. One wouldn't need too many others with the 3 of these.
