I've had a hankering for a RugerNo1 RSI for a long time but not enough to save up for one while raising a family. Unexpected funds will allow one now but all I can find are those in 257 Roberts which is a dandy cartridge no doubt but I wanted a 7x57 of a 308.(I have had a couple 257s through the years and killed a few deer with them.) Are there still some of the 7x57s at wholesalers or even retailers that anyone knows of? Thanks for any help.
