I have decided to get a varmint gun. What is the best caliber in your opinion. i am stuck mainly between the 22-250rem or the .17rem. I am open minded though. I need to get something smaller than my 270 because the selection is not all that great on varmint ammo. What caliber and brand/model of gun do you recommend? varminting looks like a lot of fun to me. What about the cci .22 stinger? well, please help me the best you can. Thanks in advance.
