Just curious if you stress the action too much what really happens? Does it develop stress fractures in the receiver itself?

Never mind I did some research. Pretty interesting point I found was to support the barrel just in front of the action for longer heavy barrels. That makes sense letting a portion of the stock take the weight of the barrel and the rest is free floated. They did mention that you could bed the barrel half way down the stock to eliminate vibrations but I don't see a 1.250" dia barrel or larger needing all that. Maybe.
