As Zimmer suggested, the brass is ancient and probably brittle as hell. I'd suggest your "mate's mate" gets some modern S&B brass (and some good advice) and goes from there

I wont pretend to understand the head space thing to be honest, but had heard of issues in the past, so thought it my be connected.
Unfortunately, `mate`s mate` is the worlds expert on everything, so wont listen to any one else.
Fortunately, the owner of the rifle is a little more open minded. I will quietly suggest he gives the reloads a wide berth
