Gee, I hate to stick my head into the meatgrinder here, but:
lobo9er: That's a great link to the Guy who did some of his own "bird shot" Gel testing. He used a real nice distance of 15 feet (not excessively long, I think apropriate for INSIDE the house defense, especially if you're in a 1500 sq ft or less house, or a typical 2 bedroom apartment of 8 to 900 sq ft)). He also used a modified choke and Mossberg 835. He used 2 layers of Denim in front of the Gel block (and leaves us to assume its 10% and he used a BB Cal shot, and it met the standard--neither mentioned)
But the point to remember, while he calls it "Bird shot", it is, just barely. It's very large "Goose/Crane/Turkey" shot. Not your average bunny or even pheasent buster--let alone a quail or Clay load. He used size F steel (.22 in dia: #4 Buck is .24) , and BB steel. Both are or EXCEED what can be expected from #2 Lead at the same velocity. The maker, Federal, list the velocity at 1450 fps on the BB (3" 1 1/4 oz BlackCloud) He does use a #6 2 oz turkey load, but from a 3 1/2 in shell. I can't find this load on Federal's website (maybe it's discontinued? Cheaper Than Dirt lists it, and claims 1300 fps--I'd rather see that claimed by Federal, but such is life...). While shot size, material (lead) and velocity might be considered to be a (old time/pre ban) Duck and Pheasent load, 2 oz is a LOT of shot.
You got to ask yourself, Will meat and bone be disintagrated like the Gel Block was? About 3 #6 pellets made it 10 in, most are back at the 6 in area. It's like the leading edge of the shot string clears the way for the shot behind it. Other labs/peoples tests with 1 to 1 1/4 oz of 6 or 7 1/2 lead certainly DON'T show this kind of performance on a gel block. Also, this load uses a "flight control" style wad and the pattern at 15 feet could be smaller than expected from a standard plastic petal wad.
What's the recoil/shot recovery going to be like on a 2 oz 1450 fps load? Hocka Louis' 12ga 3 in 15 pellet load would weigh about 2 1/4 oz but at only 1210 fps. (I assumed 65 gn per pellet)
Hasn't "The Box of Truth" testing pretty much shown (considering the F and BB loads that exited the gel block) that anything that meets FBI min standards IS a threat to anyone in the next room, 2 or 3 "walls" away? So we may have finally found a "Bird Shot" BIG enough and FAST enough that it truely is a manstopper--It might as well be 00 Buck to the sleeping persons next door....
Just things to make you go, "hummmm".
