Mike Jennvey, it was you was it
.
I used to fire the sterling every chance I got. I had one case where the bullet came out through the extractor together with fragments of casing. The previous round then hit the target having had a kick up the jacksie.
The case for that round was an interesting shape too. It was a few mills shorter and had a fat ring around the middle.
Fortunately I was on the right spot when firing.
