I have a friend who enquired about 12 ga. "shell crackers" a few days ago. These are the noise making loads for chasing off nuisance birds and he was trying to find some for his rural property. I sent him an ad I found on the internet and he checked into it and just emailed me, saying that evidently they are now under federal control since 9/11. That is, you must have some sort of ATFE license and an approved storage area. Now, this information came from someone in his area so I'm not sure of its validity. Can anyone shed some light on this?
