The beauty of buying that RSI in .30-06 (I hope original poster did buy it) is you're getting the long action which Ruger also used for the .270 Win caliber. I'd classify them as at least semi-rare. I have one I picked up probably 20 years ago, it's a Mark II.
To further my tiny RSI collection I acquired one of the Lipsey's special run rifles in .308, at the time there were a few in the various calibers Lipsey's had offered, all in stainless steel, all short actions.
Recently, I saw that Lipsey's had again commissioned a run in 6.5 Creedmoor, I couldn't resist buying one. It's stainless steel and short action.
I, too, mourn the fact that Ruger took the RSI out of their catalog. I prefer the bolt/extractor type patented by Paul Mauser over 100 years ago, and the full length stock. I've asked Andy to make a leather Rhodesian sling for the newest one, brush nickel finish to match the stainless steel.
