Bullet base markings

i was inerting some 0,303" today and found this mark on the base of one of the bullets. It’s not one that I’ve seen before and it’s not included in any of the printed references I have that deal with the subject.

It was loaded into a case headstamped ‘RG 1942 VII’

Does anyone keep a record of these marks?

Happy collecting, Peter

The star or asterisk base mark was used by Royal Laboratory. They also used a broad arrow and a circle, but which cartridge factory within RL used each mark I do not know.

It is listed in my .303" headstamp guide.
