I would just like to clarify if you are looking for an old tang safety model or a newerMk II model? I have an old tang safety RSI in 243 and love it. I have seen one in 270 and one in 250-3000 Savage in my travelsbut never 257 Roberts. These little guns are very hard to find and usually command a "premium" price. I bet that a RSI in 257 Roberts would be a SWEET little gun. Good luck with your search!
