You just want the action? the 7RM, 300 WM, 338 WM, 264 WM are all the same as the 8 RM, which is the same as all other Remington long action 700s except for the bolt face, which only needs a light touch up to work.
leverite is correct. I'd go to Gunbroker and Auction Arms. In the search window, type in 8mm Remington and everything in that caliber will pop up. Put them on your watch list. You'll see if they garner any bids.
You'll probably see alot with reserve prices that get no interest at all. I was thinking of getting a 375 Ruger that an aquaintence wanted to sell. What I found from this method was that there was little to no interest in 375 Ruger. 375 H&Hs got bids and sales but not the Ruger version. I already have a Model 70 in 375 H&H. I'll ending up saving that money instead for a Shiloh Sharps!
