I posted on another thread about having trouble with my arrows penetrating almost through a new block target. In retrospect , it was a friends and now I' m not for sure if it was a Blackhole or a Block.

Anyway after reading this thread I decided to try one myself and I am pleased so far. It is stopping my arrows very well and I am shooting a 352 grain arrow @ 296 currently. Just thought I would let ya' ll know !
