Federal 12G grand slam turkey ammo

I have 3 boxes(10 shells per box) of factory 12 gauge 3 1/2 shells with a 6 shot size for turkey hunting.

These are interesting shells, they have a clear disk holding in the shot and buffering material. This allow for a better and more even pattern. 

3 boxes available                                                              
2 boxes sold  

$90 for all 3 boxes or best offer. Can meet up in York Region. PAL Required.
