....Craigd, The reason why proof is valued by most shooters in the CIP area is that we CAN go into a gun shop and if the box of cartridges says it is suitable for the chamber length of our gun, we can use it with impunity. Obviously, once the gun leaves the CIP area, eg goes to the USA, there is no such standard and ignorance of what a suitable load might be could get someone into trouble. I make no criticism of the situation in the USA, I just try to manage the risk as best I can.
Thank you for the follow up comments. I think this is a good thing, now the shooter is engaged in what they're doing. Still, if in proof for 'standard', that alone doesn't prevent the chambering and firing of a 'superior' load.
In your opening comment, you mention that in recent years you have become accustomed to more barrel failures, though this example is different. Do you have any thought as to how much more pressure is involved with 'standard' proof? My understanding is measurement procedures have changed, so the proof loads are now different? If the guns are failing more often than in the past, is there some thought that the guns that pass have a better safety margin? Do you have any concern for the possibility that a future change happens that results in a higher failure rate than currently. Sorry for all the questions, I just find it truly interesting.
