[QUOTE="Garycrow, post: 924577, member: 30743"] Not all stainless actions have chrome moly bolts. Most of my rifles are Winchester M70's and their bolts are stainless. I have had no problems with galling, keeping the lugs properly lubed will stop any galling tendencies. Everything's a trade off. Stainless actions are plenty strong, if they weren't then most custom actions wouldn't be made from stainless. Heat treating plays a major role in the tensile strength so it's not as simple as saying chrome moly is stronger than stainless because it varies with the individual pieces. Depending upon the heat treating, a stainless action might very well be much stronger than it's chrome moly counterpart. Another metric is fracture toughness, resistance to fracturing, in which stainless is generally superior to 4140. Stainless actions have been in use for many years so it's safe to say that the strength of stainless is a non-issue. Yes, you can coat, nitride, or treat chrome moly in various manners to improve corrosion resistance but why bother with that when you can get the properties you want by using stainless. Also, coatings like cerakote wear off in high use areas after a while and I personally am not crazy about the painted look. The only reason not to use stainless for an action that I consider to be halfway legitimate is some people find chrome moly to be smoother. I haven't noticed that effect but if it's something that bothers you in an action then that would be a reason for using chrome moly. [/QUOTE]
