Hey, the Block 4X4 is an awesome target! It has withstood the Magnus Stingers without any problems at all. It self seals too so all you see is a little "pock mark" after a while. The Slick Tricks pound the Block 4X4 and don't come out as easily. They will tear the insides a bit upon removal. Regular field tips are no big deal at all with the Block 4X4. You could shoot them thousands of times without any affects on the target.

I highly recommend the Block 4X4. It's really a great backyard target! [8D]
