ISSF secretary general Franz Schreiber is confident the shooting competition at this summer's Olympic Games will run smoothly despite one or two teething troubles at the test event.
The ISSF World Cup at the Royal Artillery Barracks came to an end on Saturday after 10 days and 15 events featuring more than 800 athletes.
However, the temporary venue is still not complete and the constant rain at times made parts of it resemble Glastonbury rather than Woolwich.
A voice-activated trap also broke down during one event, while local foxes are said to have chewed through cables and left 'deposits' on the medal podium.
Chinese shooter Du Lin, who won a bronze medal in the women's 50m rifle 3 position event, was not impressed, saying: "I found the venue below my expectations.
"It is rundown and not ready. The weather was too cold and noisy."
But after the Saturday's final event, the men's 50m rifle 3 position which was won by Italy's Niccolo Campriani, Schreiber said: "The test has been successful.
"The installation proved to be working very well even under the pressure of such a massive event. It is a great venue.
"We had more than twice the participants than at the Games time, when 390 shooters will be competing here.
"There is still some work to do to tune up the venue, but with more than 90 days to go there should be no problems."
