Cheers, Nick and Jim.
I will be making a suitable A4 target holder tomorrow after I have had another look through the rules (on the new website). I've also found a spare magazine which will fit my 1911A1.
I assume that if a shot touches a scoring ring, then you get the higher value? As wadcutters are obvioulsy out of the question with airsoft, what I propose to do is place a BB over the entry hole to see if it touches a scoring line.
All the best.
