What mods need to be done to get a 300WSM to feed in a 700 action that was a 7mm SAUM? Right now the first rounds just pops straight up and the feed rails don't hold it as soon as the bolt starts forward. Second rounds feeds just fine.
 
That's what I'm running. My stiller predator feels like butter with the same setup. Are feed rails different on the 700? Seems all the same. Are the followers the same?
