I am gonna throw in the measurements from above as a reference. Post soon. I don't think anyone is a trying to cheat, and in all reality, this is for fun. I have got some pm's and stuff from yodave and he is gonna hopefully get me some precise measurements form a couple points on the target. I am not here to trash or discredit the guy but we don't need 4 pages of doubts and comments. We will figure it out and move on.
Measurement I give may be flawed..........that target is from a print shop, it may not be a true scale of a IBS score target, 10 or 20 thou difference on the score lines could be the make or break of the target, as with Calvins measurements...he didn't get a full .750 from 10 ring to 9 ring but slightly smaller, so adjusting your scale slightly smaller would infact make the group smaller, we are splitting hairs on how close it could or couldn't be...........
