Steve i think it boils down to personal honesty really
lets say you could do what you said which will be against the rules of ukahft would you do it ?
99.9 % of this sport is self policed anyway and we should be able to trust the competitors to do so
for them selfs but if as normal you see someone touching thier scope for no reason then ask if they have
cleared this with thier fellow shooters as Gary has stated.
rules are rules and i for one am glad that in this case that common sense has been applied to this rule.
