This one was not too bright either. I was able to lip squeak him in from a few hundred yds away and a red LED on him the whole time. In my experience they are usually much more cautious than that.
I put a suppressed 3050 fps 53 grain VMAX round right into the boiler, from head-on, at about 20 paces. It made an entrance and no exit. That was a first, as VMAX usually makes a mess of things on Bcats.
