Club members participate in the Yorkshire Benchrest 25 yard competition for rifles (see https://yorkshiresmallbore.org.uk/leagues/bench-rest-rifle/).
The rules are slightly different to other leagues and my be found here.
In summary, the rifle may be supported on a rest at the front, but the rear must not be supported on a bag or the table.
Any type of rimfire or air rifle may be used, but each shot must be manually loaded (not from a magazine).
