Block Infinity Target (Size: 20")

I bought this target because it says it will stop a 500 fps arrow. WeLL my crossbow goes 410 and the very first arrow ever shot into the target , the arrow went in so far that only the last 1/4" of the nock was visible. I had to pull the arrow out from the back and I am sure it was not good on the plastic fletching. I will be returning this target. It cost $200.44. I bought a target from Fleet Farm on sale for about $43 with tax and is rated at 425 fps and I shot my 410 fps crossbow at it about 10 times and it stopped the arrows really good . It is just a 20" Speedbag. I would not recommend the Block Target.
