I would use the TMR reticle. I have a couple of Leupolds with that reticle, and when I use it in conjunction with my Exbal ballistics progam, the program runs the impact point for each of the 10 hash marks on the reticle. It looks something like this:
X hair = 100
bar 1 = 136
bar 2 = 167
bar 3 = 212
bar 4 = 236
bar 5 = 258
bar 6 = 297
bar 7 = 341
bar 8 = 392
bar 9 = 428
bar 10 = 517
Of course the impact points change for each load, and cartridge, but you get the idea. If I want to shoot something at 267 yards, I would hold bar #5 just a wee bit high. Although not as precise as dialing up the elevation changes, it is far faster when time is an important factor.
I place a printed version of the impact points on the rifle so I can easily refer to it. I have one chart with come ups for every 25 yards, and then the reticle impact points. In my shooting kit, I keep a much longer version that shows the impact point for each quarter minute of angle out to about 750 yards for target rifles, less for closer range rifles like the 5.56.
