I recently purchased some NOS (New Old Stock) RH_M700 LA bolts with the 338 Lapua Magnum bolt face. These came with an M16xtr as an OEM standard.
Bushing a bolt nose to a different case diameter, especially how we do it, isn't the easiest thing to accomplish as it requires an elevated amount of fuss in the setup to ensure your finish work blends well with the existing extractor pocket. I've done this on a "fat finger" basis just because we don't see it too often. (meaning I just bully my way through the CNC setup code to get what I'm after) Now that I have a box full of bolts to sell, it compels me to sit down and dedicate a program to it.
Long story short, if you have one of these and wondered about changing the cartridge to something more suited for the M700, it's now a practical option.
Happy to help.

The AR-15 /M-16 extractor upgrade for an M700 bolt is a very popular and almost required service for several applications. When working with magnum bolt face cartridges, the AR-15/M-16 extractor is almost a must-have as the riveted factory piece is prone to be problematic. The AR-15/M-16...
