Mossberg 500 with 2 3/4 federal 00 buck
You think you're kidding but I've read stories that when the A10 Tank Killer fires it's Gatlin gun the aircraft does decelerate. So I guess in theory that if it was flying near stall speed and it fires it's gun it could lose lift.
I agree, unlikely to happen. My "stall" comment was just a theoretically possible thought. I know our A10 pilots are smart enough not to do such a thing.Unlikely to happen since the gun is primarily used on ground targets which would allow the aircraft to "coast" if you will.
Winchester PDX1 is the way to go. I did some testing with it, and was VERY impressed. I was even more impressed with the results from the FBI tests.
