[QUOTE="IdahoCTD, post: 1438815, member: 13110"] I have 2 300 Norma Imp's on Remington actions and it's not as easy as a new bolt or opening up the existing one. A Norma case won't fit between the feed rails of a 300wm action so quite a bit of work needs to happen there to get them to feed correctly. The 300 Norma is only 2.5" long compared to the 2.62" of a 300wm. The barrel would have to be set back two turns to clean up the old chamber provided the neck diameter on the Norma is larger then the 300wm. A factory reamer is but my reamer, for a tighter no turn neck isn't. Otherwise it's a rebarrel. One other thing......there is a reason Remington only makes their 338 Lapua guns on chromoly actions. I wouldn't do a stainless action. [/QUOTE]
