I saw a gel test on YouTube for this bullet done by AR.com and he was shooting from 10 yards away and still got 10” of penetration. I would think that at 223 speeds at a farther distance, penetration would improve. There are several individuals who are doing gel tests who shoot at 100 yards, and in my opinion this is a better approach. I would like to know what distance the FBI tested at.
Edit:
The FBI shoots into the gel from 10ft for their test. I do not think that this test translates into a failure as a hunting bullet. This ballistic tip style, be it SST or TTSX, is known to promote more rapid expansion. At 10ft and doing essentially the muzzle velocity, of course it’s going to come apart and penetrate less.
