guys,

the block and black hole are only made to really shoot field tips in that's it!!!! it will last you almost forever!!!! If you want to shoot broadheads use a target like the cube which is made to shoot broadheads into or I hear good things about Morrells yellow Jacket target.
The cube is made by American Whitetail company, it has it's drawbacks also if you shoot field tips in it you will need a crane to get them out because of the bonded layers it is made of but if you shoot broadheads they come out easy!! this is what i use 2 different targets for 2 different heads, my block has lasted 3 years with no sign of falling apart yet and my cube 4 years now..... just my .02
