Does anyone know if this can is from a tender to the UK MOD ?

The manufacturer is not one I had heard of before, EPA Manufacturing Ltd.
Apparently they are based in Lincolnshire, UK, and have also branched out to Pennsylvania, USA.

The wikipedia page for .300 AAC has a reference source for a tender by the MOD dated 2017, to supply ammunition to replace the “currently in service” 7.62 x 35

Does anyone know when the UK MOD introduced 7.62 x 35 into service and does it have an L series number?

Looking through the internet for more info about .300AAC in the UK, I see that the Sig-Sauer MCX is used by Police CTSFO and UKSF to replace the HK MP5SD3.

The Metropolitan Police have tendered for ammunition.

Primetake make a range of ammunition in this caliber.
