T.K.Lee is T. K. LEE CO. - Custom Dot Reticles
I have used him often for custom reticles and have no complaints.
I use many custom, ballistic and rangefinding reticles for downrange zeroing and rangefinding and love them. They don't often match even hundred yd. intervals, but i just match the reticle subtensions to the trajectory. Here's my VH reticle matched to the trajectory of a 115 DTAC out of a 243 WSSM specialty pistol. I have made a couple long-range connections beyond 500 yds. using this system INCLUDING WINDAGE, which calcs. out at about .5 of the 10 mph subtensions--
