When I were a lad (1970s), we had .22 conversions of the SLR.
My grandson has just joined ATC and the squadron is no longer using the tunnel range for the .22. We were told that all the rifles have been taken away to secure armouries, due to some being stolen from an ACF unit premises. I fear they will never get them back, as the risk averse folks up top have been looking for the excuse to stop shooting. Stand by for some sterile compootah alternative. The squadron has also lost their No4 DP rifles as they don't meet current EU de-activation standards, so they have lost another enjoyable activity. Pfft.
