Anyone ever use Solid Broadheads? I know that they are expensive ($75 for 3) but they say that they come razor sharp and are super durable. The maker shot them through 16 ga. Steel in front of a 3/4" piece of plywood. He had to shoot it 4 times before it showed the slightest bit of damage on the tip. It looked to have great penetration. Just wondering if anyone has tried them and how we're the results on game.
