Well, the entire Norwegian national team shoot V8s with no bdc reticle now. Usually I will click to whatever setting that I can shoot center on each target for the entire stage if possible. For about like 80% of a typical IPSC match this is going to be possible, because you only have 1-3 long range stages, and for stages where you shoot targets 200-250 and closer you're almost always going to find a zero that works for all targets. Basically, a bdc reticle is not neccessary anyway. If I have a stage with plates at 150 meters, paper at 200 and maybe 30, 70 or whatever I click to 150 to be poa on the 150 meter plates, and just shoot center on the other stuff too. If theres a stage where you can't find an exact setting that works for every target I'll just memorize the targets where I have to aim high or low. Which is basically what I do when shooting anyway, normal stage prep for me is to visualize poa on every target in the stage.
At the nordic championship this summer there was one stage with 380 meter paper targets, for that stage all of us clicked to 380, shot center, then clicked to 200 and shot the rest of the stage centerish poa. Except for the 380 meter paper it had targets from 250 to 70 meters, so 200 zero for the rest of the stage was pretty spot on. For the rest of the match I just clicked the turret to the most appropriate setting for the stage and just shot it. For the few occasions where you have to click mid stage the turret is big enough so you can turn it while running almost as fast as adjusting zoom. And it's probably only going to be needed maybe once or twice in an entire match.
All IPSC targets are typically used for 100+ meters. Standard and mini IPSC targets, standard and mini poppers + large and small plates.
The ring I'm using now corresponds with 55grs S&B in my 20" barrel. 1=100 meters, 2=200 and so on.
I don't use the reticle, just the dot. Both Swaro and Zeiss have plenty daylight bright dots.
