I had a quick dabble with the centrefire one but it needs a little thought to do well in an A4 target where there isn't much room.
With an accurate rimfire at 100m groups will still be pretty tight. If you're shooting 2.5" groups by then it will still be easy to separate your largest group from the neighbouring 75m group.
Centrefire is a bit trickier though given the potential group sizes at 200, 300m etc.
I suspect an A4 target may be limited to 50, 100, 200m... Maybe 300 to be practical for most people.
A3 will be needed for 300+
I'll figure it out anyway and upload in the next day or two.
In the meantime,
the rimfire target is ready to download at the usual page. Bottom of the list.
See you on the firing line.
