On another forum a gentleman describes some test that he ran on some lever guns. A Winchester 92, a Winchester 94, and a Marlin 336 were each chambered for the 454 Casull and test fired. The 92 was made for pistol cartridges and the other two, the 94 Big Bore and the 336 were made for cartridges developing 52,000 CUP pressures, the same as the Casull.
According to the author, The 336 became inoperative after some 30 rounds. It did NOT blow up but was so battered that the action would not function.
Shortly thereafter, the 94 BB suffered the same fate.
The Winchester 92 took the licking and kept on kicking...indefinitely.
His opinion; The 92 is a much stronger action because of the square locking bars that lock the bolt. The other two were destroyed because of the angled locking bars. (oversimplified)
My question; Why did the two actions fail so early if the are designed to operate at the same pressure as the Casull? ( Both guns are factory chambered for the 356 and 375 Win.)
Any of you knowledgeable ladies or gentlemen have a definitive answer?
