I have a .350 Rem Mag. in Rem 700 with an inexpensive Remington injection molded stock. I'm thinking of epoxy bedding the action and, given the healthy recoil, I believe it would benefit accuracy. I have a large supply of epoxy on hand similar to that of West Systems (marine). I'm familiar with the basics but have had a hard time finding info dealing with injection molded stocks.
My concern is getting a good bond of epoxy to plastic.
