The Rifleman website https://www.rifleman.org.uk/Enfield_Rifle_No.8.html talks about keyholing issues with certain types of ammunition possibly due to the lead and that it was absent with one brand of 'imported match ammunition'. Testing with ICI ammunition is mentioned but does anyone know what the military would have used (some sort of Eley maybe?). I've got some CCI standard and Eley Match to try in standard velocity (I assumed the Eley is SV?) so I'll see how that does to start with.
