Late production Royal Laboratories .303

Today I acquired a fired .303 case headstamped “R/|\L 54 7”. This is the latest date I have seen on a .303 from RL. Was this their last year of production of .303 ammunition?

Hi Falcon - last year of .303 (& all other SAA calibres) production at Royal Laboratory was 1957. They were due to shut down a couple of years prior to that - but covered Radway Green while they changed over to 7.62mm x 51.

Cheers John, I seemed to remember '57 being the last date RL produced SAA.
