"I have .30 Mauser dies and 7.62X25 dies."
I don't suppose they're also the same set of dies?
"Many Mauser pistols came out of China in very bad condition, and that is an important factor to take into consideration."
This is likely the real culprit for the perceived difference in capability in the two pistols. Both were designed to operate on
very similar levels of recoil, after all. The difference is one was built by either German wizards or soul-possessed Chinese Boxers (hard to believe such craftsmanship as is required in even a
crude C96 actually predated the garbage they put out afterward), and the Tokarev platforms were inspired by a solid fifty years of subsequent design improvements and machining advances.
It's a lot easier to make a safe, in spec Tokarev than a Mauser clone. It's not unreasonable to assume that most of the guns that blew up had one of a dozen pre-existing conditions going on that are known to plague the guns, independent of nominal action strength.
All I know, is when I shot real deal WWI-period 30 Mauser ammo in my Broomhandle, the flash, recoil, and concussion exceeded my CZ52 with Bulgarian ammo. The real reason to down-load the C96 is because it is physically painful to shoot anything significant through it. The real reason to not ever again shoot WWI-period Mauser ammo is because only four rounds of twenty lit off; at least none were hangfires or smelly, unlike Spanish 9mm Largo which holds the spot for Worst Ammo Ever.
