I have to say it’s pretty fun. My son got one last summer and we’ve had some fun contests sitting on the porch swing shooting wood boring bees. Wing shooting them is the best. No sport shooting them off the rails. :-)
I can see someone shooting a fly that’s sitting on a stereo or DVD player. Salt and electronics, not good. But the good news is if you need to salt your food you can just have someone shoot you some salt.
Maybe we can film a fly hunt, and then edit it of course and make it look like we shot it at 20 yards! I'll even whisper to the camera, even though we'll film that part after we "smoke" one at 2'. I can even call that one a "Turd Donkey"!
About 3 feet makes a good enough pattern and energy to knock down bumblebees and wasps. Closer is better for outright kills. Regular salt makes for a denser pattern but shortens the effective range. We’ve been using the more granular kosher salt for more knock down power on the larger insects at longer distance. 5 feet is pushing it.
Sons frat brothers got him interested in it as they shoot insects around their house and when grilling outdoors. And have competitions shooting flys.
But when he brings his home we shoot those boring bees and wasps of the porch. It is pretty fun while waiting on burgers or steaks grilling.
He’s spent his money on less then worthwhile stuff. :-)
