After completing my first PVC Dart, I found that it wouldn't fly perfectly straight.  The nose would head in the right direction but the tail would just spiral behind creating random flight paths.  This just wouldn't do.  I needed a lot more weight in that nose to pull the tail.  I looked upon it with this analogy.  If you through a foam ball as hard as you can in any direction,  it isn't going to travel very far.  But if you throw a baseball of the same size, it is going to go a whole lot farther.  Unfortunately I severely under estimated the range of this projectile.  I put it in the bazooka and pointed the bazooka almost straight up.  The dart quickly climbed and peaked of an unknown altitude. The dart landed at about 600 ft. away from the launch site.  I haven't exactly found it yet.  It is some densely wooded slope.  Hopefully when the leaves are gone and the snow melts I'll be able to trace it.  I had absolutely no idea that this steel head would improve range and accuracy so much!  I have yet to test this projectile on a stationary object for damage. 

The galvanized steel head was the only modification made do the PVC dart but improved the dart's overall performance by at least 150%.
