Nice history of the #5 Mark 1. I have a #4 mark 1. This is the most accurate rifle I have compared to all my military bolt rifles. The .303 Brit. is a great round.
I noticed the pic of the cordite. I purchased some .303 that were marked 1943 from Greece. I figured I would pull the head off and when the strands came out I was shocked as I didn't know what it was. I counted 26 strands in the case. I ran a few out to the Enfield and it worked w/no problems.
Thanks for sharing the pics and info.
