This is the construction I use in my target range map:
A 20x20cm steam grate item on the 'face' of all the tall silhoutte targets, with events connected to each that wins goals and advances the waypoint.
Hopefully, that makes this screenshot more understandable:
You see the ammo counter. It took me six rounds with velocity 340, drag 0.993, weapon error_up of 0.017 (2 moa groups) to hit that 2.29 moa wide grate from 300m.
'Cause what I'm calling the 'dropring' targa is not really a Trijicon RTR .223 or an RTR 9mm PCC reticle, but it's heavily inspired by them, adapted pretty friggin' well for the job, and make the M4A1SD in the TIOCoop mod a joy to master.
The horseshoe and red dot are zeroed to 50m, and the hashes on the vertical are POAs for 100m, 200m, and 300m. The POIs are all within the POA pixels they need to be in, and I can work with this reticle, even at 1.25x (1.34x?). The horseshoe's inner diameter is dude-wide at 50m, and I initially had the hashes dude-wide at range, but the 300m hash got too faint to be useful, so I made them all 3px wide.
It's a knock-off, but effective.
