D1 Target Dimensions?

[CZ52GUY]

Hi,

A few weeks ago I found a very detailed "schematic" showing the dimensions of a D1 target. I figured with a compass, boxcutter, and T-Square it would be fairly simple to make a few with scrap cardboard.

Anyone know where I can find this info' on the web?

I'd like to set up a GSSF equivalent course at a back yard range.

Thanks in advance,

CZ52'

p.s. Never mind...found it here:
