That bullet did not go thru the first two jugs with that flowery nose. Odds are it 'finally' opened-up and blossomed inside that third jug.
This Barnes design is virtually identical to the once popular Buffalo Bullet lead design, that often was given low grades 15-20 years ago for it's lack of flowering at high / magnum load speeds.
Perhaps Ron could conduct another test of this bullet at lower speeds..... enough lower where the bullet flower shows itself inside a 2nd jug and not the third. Doing so may recover more of these bullets inside your our next whitetail deer captured during hunting season.
