Actually 12 TBH sub 6ft-lb which is legal to use in germany from 12 year old so if a junior was to get a place they could legally shoot that gun it would make a mockery of the competition. But rules are rules and i see nothing on the site for the 2013 worlds to state anything different. I just had a thought what if a junior at the age of 12 won the junior title in norway .How would they defend the title in germany ???
