Honestly, and maybe I'm too pessimistic, I see the Sig system as encouraging unethical behavior. I think for a lot of guys there's going to be a temptation to take shots well beyond what they have practiced and/or verified. Consider the following scenario:
Hunter has this system, he's zeroed and confirmed drops out to the 300 yard max range he's got in his home state back east. He doesn't realize he's 100 FPS off what the box claims for his ammo, because that's only about an inch difference (well inside his group size at that distance).
He's done his homework reasonably well, he thinks. He ranges and shoots a 10" rock when he gets there, 450 yards. Hit! He was towards the bottom of the rock, but a hit is a hit, further than anything he's ever shot before. "That's my limit," he says to himself.
Last day of the season, after a week of hard hunting, a buck steps out at 525 yards. Only 75 more than he said was his limit. How many hunters will resist the temptation of that little glowing dot of not-so-long-ago-NASA level ballistics calculation and computing power saying, "just hold here. It's easy!"
That 100 FPS is now 5" more drop at 525 than what the computer thinks, and we haven't even started talking about wind.
There's what I think is an unwarranted level of confidence in the technology when it puts the dot in the reticle. I think people have a much more reasonable understanding of their capabilities when they put a drop chart together or at least run their own calculations and turn the dial themselves. I think turning that elevation turret further than you ever have before is a much bigger deterrent to taking that unethical shot. I think people will put too much blind faith in that dot for a 600+ yard shot because the technology says "hold right here."
