I agree w/that probability, Stan. Also regular pitch targets can become rock hard when left exposed to the elements over a long period of time. When you see orange pitch targets faded to near white, you best bet they will be VERY hard to break.

I attended a trap shoot two summers back that was using some bio targets that were not prone to breakage when hit. You could literally see them move a couple of feet when hit, but they didn't break. Many of those same targets were picked up afterwards and had as many as seven distinct pellet strikes on them. We took some of those same targets and threw them at the ground; they still did not break! That was an anomaly, long since dealt w/by the maker, but bios remain harder than pitch targets, even when fresh, and I don't think anyone will argue that point.

Glad that you bring it up! Thank you for doing so.
