You say 'easier' Steve but we were pretty inventive back then!
Remember we were allowed to hide 50% of the kill....Now put that kill in a 15mph wind behind a fencepost at 45yds and you had a scary target!..
I think 15mm targets came in to 8yds as well didn't they!?
Overall i think it is definitely harder, the 25mm's at 40 yds guarantee that i guess and of course the 25mm positionals and 6x15mm targets..
