In my thread on .22 Target Rifles, a lot of the replies were about shooting BSA, Remington, or other military training rifles.
The US Army has used .22 club target rifles off and on, the latest being the Kimber in the 1980s. They have used Winchester M-52, Remington 541 and 513 and others, Mossberg, Springfield Armory, and for a little while in the 1980s they used a .22 LR adapter for the M-16.
In my collection, I have a New Zealand .22 LR training rifle built off an Enfield No. 1 MkIII and a CZ built like a little Mauser.
A friend has a .22 LR Enfield built by BSA off a No.4 MkI, with a 5 round clip.
He also has a German Mauser .22 LR training rifle for the K-98.
Recently, there are dedicated .22 LR in the size and feel of the M-4 carbine, the Sig 556, HK MP5, AK-47, and pistols like the 1911A1, Glock 19, Beretta 92, SIG 220, etc.
I am really wondering how common the .22 LR Enfields are in the UK, and who might hunt small game with them, or just shoot targets for fun/
