[QUOTE="long ranger, post: 184539, member: 800"] 7mm If planning to build a 338 Lapua or Edge I would certainly recommend going with a CM action, I have had some high end SS actions where the bolt lugs have been galled and been set back from pressure. CM is a harder and stronger material as J Jones points out. I would still favor a SS barrel for ease of cleaning and longevity. Bead blasting the finish on both materials gives an excellent base for coatings to adhere to. On CM actions I parkerize the action 1st to get corrosion protection inside the action then Cerrocoat all the external metal parts to match the barrel I use Cerrocoat and it is very tough, comes in many colors and is easy to use. As long as there is ZERO residual oil in the metal it bonds to the metal very well. [/QUOTE]
