I'm not sure they will last longer than a Block - they just cost less. And for the amount I shoot broadheads, the concept of having an "eternity" type bag target for field points and a specialized broadhead target for pre hunting season tuning makes sense. My Block 4X4 is has had hundreds of broadheads through it and thousands of field points. It has a couple of fist size holes where I shoot the broadheads into it - and it is getting to the point where occasionally an arrow will poke out the other side. So far I haven't had one actually pass through. When it is gone, I will probably get a Morrell Yellow Jacket Broadhead target and just save it for broadhead practice. The Morrell field point bag target is still goingafter more than ten years of use.

After the target gets a few thousand field points through it, the arrow will pull out with moderate force.
