"the pressure of 10mm is lower than 30 carbine"
The case head area of the 10mm is about 25% larger, so the load goes up by that much (the max pressures are fairly close). Now, it is extremely likely the gun was designed with
at least that much margin, making the change perfectly safe. An example would be; pretty every wildcat conversion ever done
.
Nonetheless, it would be wise to proceed with caution and check for lug setback, cracks, and other issues, since you
are going past the original actual loads. You are off the beaten path; proceed with caution. Since others have done this and met with success is no guarantee, but it strongly suggests that the action does indeed have sufficient extra design margin to handle a higher bolt thrust. This may wear the gun out in fewer cycles, but that point may not occur within the expected operating life of the gun, anyway (for example; it may now fatigue out at 50k rounds instead of 100k)
As I post on most all gun-modding threads here now, check out Weaponsguild, since your idea will be met with far less skepticism (none), and you will quickly get in touch with dozens of folks who would be willing to take your money for a conversion, but even more eager to show/help you to do the conversion yourself. This mod would be considered "tame" by their standards (compared to opening an AR15 boltface to accept a cut-down 300WSM case loaded with 500gr .510cal slugs at 40Ksi)
