Has anyone had their broadheads damage the arrow shafts? I've been using swhackers and swat broadheads and when the blades open and swing back they have been hitting the arrow. With the swat's I use a 25grain collar behind them and I have broke two of them in half. Today after shooting one of the swhackers I noticed the arrow had a fracture right in line with where the blade opens. I know the swats are popular, does anybody have a fix for this?
