I suspect any outfit assaying to produce a new firearms product would have tested many, many, pre-production models to destruction, and would damn well know what to recommend and what to avoid.
I know that in testing the Garand for ultimate strength, the U.S. Army concocted special proof loads that went up to 125,000 psi, the highest that could be measured with the pressure guns. They couldn't get the Garand to burst, although other damage occured. So they figured that was a pretty safe gun.
I also suspect that a lot of muzzle loader enthusiasts might not be too familiar with smokeless methods and dangers since many of them might be prohibited persons. After all, black powder's ultimate pressure is only 25,000 psi.
Naw, I can't imagine that an outfit as old and experienced as Savage would be likely to put out a product that was known to be dangerous within its recommended parameters.
Especially nowadays.
I just hope the rifles they broke in their testing and experimentation aren't called in as evidence of their "carelessness." I could see a hungry contingent fee lawyer pulling that kind of stunt.
