Wow, lots of fire, little light here. While I am sure very one who has posted here has far more experience than I do running night drills through the house, running night drills in the dark at the range, what will or will not blind/deafen you at night in the house (enclosed area) from actual experence, than I do, but if I might ask a few questions, so I can learn from all the expertise here.
Have any of you gone to the range and set up a series of note book paper (8 1/2" x 11" should be fine/will work, bigger is, of course, better) at 5' with one straight behind it at 10'-15'-20' on out to 10 yards or so (I get tire of lining all of them up on cardboard boxes, but YOU do what YOU want, more, less, what makes YOU happy. If YOU are happy, I'm happy), and then shooting (I need to be sitting or prone so everything is lined up, I don't have enough stands to get them all high enough to stand, which of course would be ideal), so gun barrel, target, back stop, are lined up to actually SEE what YOUR shotgun does with various loads (bird shot, 00 buck, #4 buck, slug, whatever, maybe a Dragon Fire for fun, but probably not out of a gas auto though) at various distances, so you ACTUALLY know what your gun does with what?
DO you need to aim a shotgun, or does "pointing in the general area of where you heard to noise" (which I am assured by nearly everyone, who admits, eventually, they have never tried/done it, claims is/does work fine) actually work because "the shotgun will spread so much it doesn't matter!" at 10 ft to maybe 30 feet (or as far as your house has straight aways anyway).
Maybe lean a few sheets of plywood together to make a "hall" to shoot through at night to test for flash/bang? DOES the flash blind you? DOES the noise (concussion) about "knock you down"?
Ever tried "shooting them in the eye" with turning/swinging targets at close range? In broad day light? At three feet? 5 feet? In the dark? At three feet or maybe 5 feet? I love hearing about how everyone is going to do that when they can barely keep 5 shots on a 3'x3' target at 10 feet after running (or walking) in place for two minutes to get the heart rate going. (But I'm sure you can do a 5 minute mile and hit a 3" target at 10 yards with 10 shots at minute 6. Me? I'll be about ten minutes behind you, to back you up, so don't worry.)
Pleae let me know, I am wondering!
