Well done ! It's something I've contemplated on doing as a hobby, although it seems easier to do this with airsoft equipment than real firearms here in Europe.
Yup, informal competitions aren't easy to do with "real" firearms here.. But if you'd ever feel like going serious it shouldn't be much of a problem to get some time with them, if you've done airsoft at least semi serious you oughta have some of the trigger discipline on point already
