I ordered one yesterday (when they brought out the .257 Roberts I bought one, only to have the stock smashed during delivery). What I've been holding out for in the stainless RSI is a .358 Winchester, but the Lipsey's product development manager said Ruger won't make an RSI in anything bigger than 30-caliber.

Initially I was going to buy the 7mm-08 (which is fantastically accurate in the bone-stock Ruger Frontier I bought for my kids) but made a last-minute decision to get the 6.5x55 Swede. I've heard lots of good things about that cartridge and its "gotta see it to believe it" performance on game.
