I have been making 10 posts a day on gun forums for 15 years.
I have been buying hundreds of guns just to overload them as a hobby for 10 years.
I am surprised at the intelligence that went into most of the posts on this thread.
I have been conditioned to expect fear and ignorance on this topic.
As stated by others, the action may be able to take way more pressure than the brass, but if the case head fails, the action may not tolerate the gas cutting.
The above pic is me overloading LC 308 brass in a 98 Mauser 10 years ago without incident.
The handling of gas from the primer pocket is excellent in that design.
But in the last year, I have had 98 Mauser extractors come back out of the action like Shrapnel (3) times.
It is very different when the primer pocket expands, than when the case head comes off.
