It didn't take too much time to revise/update the fixture. Cut the bottom and made a hinge from belting. It opens like a clam shell. Put a new end on it with a piece of 2" hard foam insulation as a bullet catcher as the over all length is considerably shorter after the "big bang".
I thin the reason for the big bang was the brittleness of the pipe. It had very little flex.
Here's the setup:
Nothing is solid this time. Also the bungie cords are tensioned very precisely. Note the blue bullet catcher.
Wrapped, tied down and ready for a shot.
300 yd zero looks close. Wow, no damage. (Grinnnnnnn)
Things must have flexed sufficiently. No loss of media. All the media was well loosened which indicated the bullet went from one end to the other. With less explosiveness due to change in fixture I suspect bullet performance to be slightly different.
Next post. The bullet.
