The problem I have with the drop compensation reticles is they can only be accurate in one set of conditions for a given load.

I do quite a bit of traveling for work, and do as much hunting as I can while on the road - or at least do as much networking as I can so I can come back and hunt later. I have a pet load for one of my coyote rifles that I hunted in 3 different states in under a month last season. I was about 5000ft higher than home in Colorado but at the same temp as I zeroed at home 0*. The impact moved about 6" at 400yrds. Then I was at the same elevation as home, but drier air and mid 60's to low 70's instead of zero; impact changed again on me.

So even shooting the same rifle and same load, if I were using a compensating reticle and tuned my load to fit it at home, it would have made me miss coyotes in Colorado and Arizona.

So I don't have any use for them. I own a few because they were cheap, but I never use them as designed.
