Coached by Colin Mallett and Bruce Horwood, the JRC scored 624 ex 630, a score that would win the final at Bisley, Surrey.
Last year the JRC placed second out of all the rifle clubs in Britain and look set to put up a strong challenge for the Astor trophy again this year.
The competition, which is shot over distances of 300, 500 and 600 yards, is open to all rifle clubs in the British Isles, with teams of six shooters and two coaches.
No more than two shooters in the team may be Class X, the top National classification, and no more than two must be Class A, the next highest target rifle classification.
Mary Norman and Ian Jones both scored a maximum 105 out of 105 but it was Norman who had an incredible 20 of her 21 shots in the centre bull (V-bull).
Said Jersey team coach, Bruce Horwood: ‘We always do well in this competition and in recent years have had several winners and runners-up medals at the National finals at Bisley.
Guernsey fired superbly too and may well qualify for the finals as the highest scoring loser.’
