I dont agree with birdshot as a strategy and wouldnt advocate it.
I have however said if its what you have then use it, but there are "if"s and hypotheticals involved with using it. It could work, but to call it the "most devestating"... I would not.
Milk jugs with water will blow dramatically with nearly any load, whether 12 ga. slugs, 00 buck, birdshot, or even .410 000 buck.
I liked and enjoyed the video however, thanks for posting it!!!
