A question if you please.... If the targets are 12 x 18, how big is the 4 MOA circle (the 8-ring) ?.... It must be exactly 4" to be a legal NUAH 100 yd. target.... They are intended to be printed from the .pdf file on 8.5 x 11 paper at 100% of size.... However, if you wish to print a NUAH target on 12 x 18 paper for use at longer ranges, I can supply you with one that is good out to 250 yards, with the ranges marked on it.... For 100 yd. the 4 MOA ring is 4", for 150 yd. it is 6", for 200 yd. it is 8", and for 250 yd. it is 10".... I can send you a .pdf file by email....Bob
