No pieces come out
They will eventually. I have a Yellow Jacket that's got a good 300 shots on it at just the two 'big' sides. I haven't punch a hole in either of the sides yet. I recommend shooting spots all over the target as opposed to groups. You'll get mor life out of your arrows, broadheads and taget this way. I shot a field point into it just to see.....just don't do it!
When I buy a BH target I'm never going to buy a Block or Black Hole....they're too expensive. No targets handle broadheads well. The very nature of slicing the things to pieces has me wondering why anyone would even think otherwise. I buy the most affordable target with the most surface area. I bet I get two+ years out of my YJ....maybe even 3!
