Beans,
As stated, the testing was done by Tom Armbrust of Ballistic Research in Illinois. All I can do is try to lead you to the data for you to read for yourself.
Not only was the testing NOT "nonscientific" or "uncertified," as you blindly guessed, it was done by a man who does this and other types of load and pressure testing...AS A BUSINESS.
There is no superiority here...we are all students. Which is why you just cannot speak so resolutely about matters on which you're only supposing...without embarassing yourself.
Lots of guys do real research here, either 1st or 2nd hand. Opinions can be quite valid, but in the presence of hard data one is wise to at least reconsider his 'best guesses.'
These tests were about as good as anyone has yet published. And they tested many, many barrels. Bell had put out the call for donor barrels, and lots of people responded.
I spoke extensively to Tom about their conclusions. This wasn't two toothless dudes on YouTube trying to blow stuff up in their grandmothers back yard.
