You can always reduce bolt thrust, ie: pressure on the bolt, by going to an Improved ctg. design. The straighter the case walls, the less the breech pressure.

The 9.3x62 has very close to an 'improved' case design, ie: minimal taper. It's design was way ahead of it's time.
Check out the something like .474" head diameter (mine is .472" - only .002" larger than sammi standard for the '06 etc.) Check out the .454" shoulder, same as most Improved cases on the .470" head cases.

The 9.3x62 has identical capacity as my .375/06IMP that is cut oversize for normal - .472" head, and .460 shoulder. Both have a 78gr. capacity.

The Improved cases are the safest for loading in any action of questionable strength. The .308 family of ctg. follow this basic improved design of minimal taper as well, but have shorter bodies, which stick less well than longer ones in the chamber during pressure peaks.

Ctgs. of greater taper, like the .416 Rigby show pressure signs of bolt thrust/sticking long before better designed, straighter brass does, as the sloping case is less able to grip the chamber walls until pressure subsides, therefore they have and are only capable of lower working pressure limits.
