I have had good success using Steel Bed in plastic stocks. In particular a M-70 "All-Terrain" stock and three choate stocks installed on Mausers.

I had one that didn't work well. A Model 70 SS Classic in .338. My zero kept shifting around. I put the .338 in a McMillan AHR stock and accuracy improved greatly. I am guessing the recil made it flex too much.

You do have to leave a larger gap than usual [at least 1/16"] in the free float area as the stocks tend to flex more tha fiberglass and and touch the barrel.
