I'll have to give it another go then. It was hit or miss with the shotgun and me last night. Sometimes I was dropping them and others it would take 2 and sometimes 3 hits to kill. I was messing around with both all night though.
I'll have to stick with Buckshot more...but I put it on a couple times and it took 2 shots at close range, whereas the flechette was lights out in 1 shot at really far distances a lot of the time. Within 15-20 feet or so, it has 1-shotted for me like 98%
of the time.
