Possible rimfire cartridge id please

Recently went metal detecting at an old gun range that was operational in the 50’s and 60’s and found what appears to be a squashed cartridge the headstamp is HR (with the letter she overlapping and the measurements are shown below.

My 2 cents FWIW: This is not a cartridge case but it is possibly the end cap off of a container of some kind. Possibly an older brass lipstick tube.


Helena Rubinstein? Hilary Rhoda?
