Decided to shoot BH's this evening.......and had 1 arrow going nuts. I cahnged the head. Still nuts. Changed the arrow. Fine.

Didn't expect to get a bad a/c/c.....but I guess anything's possible.

Shot my last group from 40 yds.....and thought "what the heck".....I'll see what kind of 4 arrow group I can shoot. What a dumbass.
