I heard from a friend this past weekend that there has been a major change in proofing barrels in the UK now.
Supposedly they are under some new Belgium system that has raised the proof to 950 BAR and instead of pulling one trigger pulled now both are being pulled at the same time and this has led to several guns/ frames warping?
Now I am not sure about all this just asking. Not that I am sending any guns over to be re-proofed.
