Market Rasen, Keelby and Hemswell rifle clubs have been raising funds for Help for Heroes and the Disabled Shooting Project.
The clubs held a rifle target shooting competition at Kirmington Shooting Ground and managed to raise an impressive £400.
About 70 people took part in the event - including Olympic bronze medallist Barry Dagger.
The money raised will be split between the two causes.
Dave Lea from military charity Help for Heroes said: “We are grateful for the money that has been raised and thank all of the shooters for their generosity.”
The Disabled Shooting Project encourages disabled people to get involved in shooting.
Liz Woodall, from the project, said: “Although we are funded by Sport England extra funds can be used to develop the Disabled Shooting Project across the country and support more participants.”
