Whether the performance will reproduce outside I don't know. I had good groups a while ago with the lighter Defiants but they just didn't do it outside.
I will have results from my steyr and the 4.52 defiants next week. Hope there as good as yours.
Did you clean your barrel like they suggest before testing and do you know what fps you were shooting them at.
