This is where I had some issue with them last year testing them out (never used them on game).

There seems to be some variance on QC.of the steel....I had one that took a very minor ding/hit just get bent all outta shape (it went through my target, and buried in the dirt...I checked carefully and the only thing it hit was a small tree root about as big around as a dime...no rocks...or anything else...)

I had another one glance offthe top of the target (used the wrong pin)andthen glanced offa rock, and it was just nicked up a bit. Couldn't find any wobble, etc.
