<br> I regards to building a "small ring" Mauser with "better steel; The Springfield 03 is a copy of a 93 . In fact a 93 will practically fall into a 03 stock. The early 70 Win is another. Mauser used design to make up for strength. The small rings are strong enough, but will not handle case head failure safely. When the case goes gas ect comes back down the left bolt raceway and into, your face. I have seen small rings that have let go over the right bolt raceway due to gas pressure. They don't fail due to too little metal around the cartridge, or only having two lugs.
<br>Good Luck!
