I just went up and put my 6-36 MIL-C on a tripod and looked around a few hundred yards. I was surprised that I absolutely was able to use the reticle for wind on 6x if needed.
Can’t speak to PRS but for NRL I’ve had stages where I’ve given up on finding a target or two with my binos, get on the rifle and engage the targets I did find, and then with time left I stay in the rifle and start looking for the other targets. I start every stage on minimum magnification as the FOV helps me get on target when transitioning from binos to rifle.
