Ron, I see your testing came up the same again of them not opening up as when you did the 200 yard test.
When I tried them again at 200 yards with 120 gr of BH 209, all they did was go thru 6 water jugs and into a 6 x 6 that I was using as a back stop about 1.5 inches into it.
FAILED again, other than being very accurate and a 1/2" slug going into the right area. I would keep them at 150 yards or less.
