A blast from the past."Within its design parameters" is the operative phrase. The .357 Max was for sending the heaviest bullets downrange to knock over steel rams. The flame cutting was a result of people who just couldn't leave it at that and had to find out how fast they could launch ridiculously light bullets using ball powder.
For people who understood the cartridge and only used heavy bullets with stick powder, the flame cutting was never a problem. Ruger couldn't rely on all the buyers also being judicious handloaders so they discontinued the revolver.
That's a shame. It was a great cartridge.
