The Proof houses seem work on the two rule system .
Rule one , The proof house can not be wrong or in any way at fault .
Rule two , If it can be proved beyond shadow of a doubt that the Proof house is incorrect or has made a mistake , see rule one .

Always has been always will be .That include guns rejected because of dented barrels that were not dented on submission etc. unfortunately the British Gun trade association is to weak to stand up to the Proof houses and individuals meet a stone wall of denial of any fault .As many of us have discovered over the years .
