Pump shrimp?

I have yet to give this a shot but sure would like to give it a try. Pump shrimp the day before dino fishing and putting it to use the next. Very circle of life and all that good stuff. Anyway, thought I'd post my findings of how to make a shrimp gun.

I know there's others out there that want to give this a shot as well....

that looks like a great design.  I break these all the time and your design looks better than mine! I do run a full length metal threaded rod through the center of the shaft to give it more stiffness.
