The card has come out well oversized on my screen; it's 17cm square and it's called a PL14/06.
You can buy them from the NSRA shop and they are about 6 or 7p each from memory, depends how many you buy.
It's the standard card for all LSR 20 yard comps that are run to NSRA rules.
The 10 ring measures just under 15mm diameter. So the apparent group size is about 13mm. JSB round head pellets leave a hole that is undersize.
