Alan ages ago I posted a pic of a MKVII round I think it was a MW (Munitions Welshpool) it had a roll crimp instead of the normal stab crimp I've never seen another one and I never got an answer back from anyone regarding so did they trial roll crimping say for ease of production.
If anything it would have been an Aussie thing I'll have a scrounge and see if I can find the picture again and post it cannot vouch for quality as I only had an I-Phone IV at that point I upgraded last year to an 11 I think!

Postscript,
I found the round on my desk so took some better pics, you can see faint stab marks but the roll goes right around the neck at the same depth so maybe a machine adjustment don't know anyway something to discus.
It is a ball round not a reload I was correct it is a MW VII 44.

Blown up a bit it looks like there are three crimps, if the points indicated by the blue arrows are indeed each the start/end of a crimp.

The profile as indicated by the yellow arrow is noticeably deeper and more "V" shaped that the other photo where it appears the position of the case in the photo is such that we are looking at the area between two crimps?

Badly worn dies or improperly adjusted machine?
