Was looking for some 20ga. Hevi-Shot Turkey load, couldn't find any, but the gun shop had some Waterfowl loads. Looked to be the samething so I bought a box (expensive). I allways like to see how things are made. So I cut open a shell and to my surprise on top of the pellets and buffer was some seeds. I called the company to ask what the seeds were. They told me they are flax seeds they just use for filler. Very interisting the things we find out sometimes !
