There are a number of competitions available for 6yd pistol and rifle on the Umarex Boys Club.
Each competition has its own downloadable targets , one or more of which might be of interest to the OP and others. The V&O completion simulates Bell target shooting without the need for the steel plate and a bell.
Have look at what it offers at:
