I've only ever had one separation of a service .303" ball in 20,000+ rounds, and that one was a 1918 round off which I'd had to sandpaper the verdigris - so I forgave it!

I'm not even convinced people need to go out and buy spare extractor springs & claws for their "emergency spares" tin - they'll probably never need them and the dwindling worldwide stocks of these small parts will just end up being lost & unused in the junk in people's sheds. If people are scared about breaking them then they should magazine load their rounds instead of single loading them loose off the top of the mag follower...
