Opening up M700 feed rails?
I know that when you convert a standard bolt face long action M700 to a super magnum, like a R.U.M., that the bolt face needs to be enlarged, you need a ultra magnum magazine w/windows, and you need to open the feed rails.
Example; You are converting from a 7mm Mag to a 338 Ultra Magnum. You have to enlarge the bolt face, you should maybe install a sako extractor, and you order a brownell's extended magazine.
You also have to open the feed rails, right?
Can someone here post a pic of what needs opened, and where?
I know this may be a guarded "LRH Gunsmith" secret, but some like tinkering with their own stuff at times.
I guess I could measure one of my factory Remington Ultras to see what difference it has over the long action.
Anyone want to share? The proceedure is mentioned often on here.
