Keep in mind that cast bullets do offer potential as target and fire-forming options. They are not particularly suited for hunting applications.
At higher velocities, gas checks are required to prevent leading in barrels.
Gas checks work fairly well in straight wall pistol cases and in rifle cases like the 38-55 and 45-70. In bottle neck cases like the .348,
another issue raises its head. If the gas check should become detached for ANY reason in the loaded cartridge, pressure excursions WILL occur.
Lever action rifles like the Model 71 Winchester and Browning DO NOT TOLERATE excess pressure well. (They are not bolt actions.) A word to the wise.
