Dorset run an excellent open 10 mt postal league, you're too late for for the summer one as its just started but make contact ready for the winter one. The top divisions are national team level but they have many divisions which makes it ideal for juniors and beginers. Can't remember the DSRA website but just google it.
Good shooting
