Flame cutting of the topstrap was pretty common with .357 Maximum, but I gather that it was largely a cosmetic issue.1. "Beware the .357 Maximum in a revolver. The cartridge can cut the topstrap in two like an acetelyene torch and fragment the forcing cone like a grenade. That's why Ruger discontinued the Maximum Super Blackhawk."
(Fact: The Maximum Blackhawk was discontinued because it was too expensive for Ruger to produce a custom frame revolver that wasn't competitive in the sport the Maximum was designed for.)
4. "The .30-30 is marginal for deer-size game."
(Fact: This cartridge has probably taken more game animals in North America than any other.)
I hear this all the time too. The 30-30 might not be good for 900 yard across-the-valley shots at mule deer or bighorn, but that's never been its purpose. It's always been a close-range brush gun, best for quick shots at 100 yards or so. I always cringe whenever I see a scope on a 30-30 since it's no long-distance round even with the new spire-point LeveRevolution cartridges.
Funny thing is that the people knocking 30-30 will then switch to talking about the deadliness of the almost (ballistically) identical 7.62x39 round...
