Hello folks,
I don't think proofs mean much here, or what the shotgun was prooved for.
When you look at the wall thickness of rifle chambers vs. shotgun chambers. there is a tremendous difference here.
The rifle chambers are much thicker and therefore capable of withstanding much greater pressures.
Is it noted somewhere on these forums that pressure curve (fast or slower )have a profound
effect on the action during firing?
Straight cases are better than bottle neck cases where doubles are concerned except for loading and especially extraction.
Bottle neck cases exert more breech pressure than straight wall cases.
The faster the rise and fall in pressure the better.
Slower powders even at lower pressure can have an effect on the action (Pressure curve of long duration) ie. opening due to bending about the hinge axis. hence a case for the third fastner, Hidden or otherwise. May I suggest that safety should be the highest concern over asthetics?
Regards,
Tom
