I myself have found most targets unsatisfactory for broadheads so I use a tightly packed hpme made bag target with a heavy foam target behind it as a back drop.
So far my broads have went thru the bag up to the flecthing and I have had no trouble in pulling the bolt completely thru and not damage the flecthing or vanes.
I do not use the bag broad head target but a few times as a pass thru could happen hence the back stop. A couple shots tell me what I need to know as far as field tip VS broad head point of impact!!
What happened to your arrows, complete miss the target and lost your arrows or tore up from the target ?
