6Yd Targets
For an accurate scaled 6 yard target go to http://www.ubc.btik.com/p_UBC_Targets.ikml
This gets you an olympic target scaled down for 6 Yards and with enough space between the divisions for a .22 pellet to fit.
Most of the other targets I see are simply reduced to whatever % makes them the right size overall. That is to say that a 25 Metre target is reduced to 0.24 of its original size. This means that even a .177 pellet can score on 3 different zones by landing in the middle of one zone and cutting the boundaries of those on either side of it.
If you want 50 targets on an A4 sheet just keep them as single circles. Colur them if you want to but please do not try to put scoring zones on them of less than 6 mm wide.
Have fun
