If I was you, I would start using bullet points. bowhunterssuperstore has em in all kinds of sizes.
I say ditto this, but maybe you need a better target as well. I have a Morrell Outdoor range, about $80, that I've never had an arrow even poke the back side of. If you're using something this durable, and poking all the way through, then the bults may help.
