It looks like this thread has been on hiatus for too long. Last year at a LGS, I noticed a 1993 stainless Remington Mountain rifle for sale for $400.00. It had a beat up Tupperware stock; I offered $350.00 and they accepted it. I figured I would see how it shot and would re-barrel it if necessary. I took it up to the range and it shot 1.5" groups, so I decided to make it into a lightweight elk rifle.
I ordered a Bell and Carlson stock, had the bolt fluted and skeletonized by Kampfeld, ordered an aluminum bolt shroud, and a lite steel firing pin from Gretan.
I bedded the recoil lug and free-floated the barrel. It now consistently shoots the 130 grain TTSX less than an inch. Here's a pic of it on a cow elk I took the other day.
It weighs 6.5 pounds as shown with Talley lightweight rings and a 2x7 Leupold scope. Best of all, it's chambered in the hard-to-find .27-300 DCI.
