I have a 257AI that was given to me but the barrel is shot out. It is a Remington 722 short action and i want to re barrel it but I don't know what caliber to chamber it in. I was thinking about a 6-284. I also want it to be light. I was thinking a 22" #3 contour. What would the pros and cons be of the 6-284 or should I go with a .25 cal selection. I don't want to go any bigger than .25 cal. Or what would be another good antelope/deer caliber that would feed from the short action magazine?
