[QUOTE="Roeder, post: 1438487, member: 87340"] There are some custom actions of 17-4 with 4340 bolt. None with the reverse as you propose. 17-4 can be very gall prone if used as a heavily loaded surface. I suspect you would have issues with the cocking cam. Common bolt to receiver clearance is about .002 for bench rest actions, more like .004 to .006 for tactical and hunting. Some have been known to grind the bolt slightly elliptical to allow small clearance in battery and more when the bolt is unlocked. [/QUOTE]
