Wow, lots of game experience here with this bullet. I had guessed NE forums would be right place to ask this question. Thanks for the recovered bullet picture mouse. Looking at that bullet I would guess the rear section to be quite hard. Looks like the TUG's "pointy" shape of the hard lead section works as advertised and causes the softer lead to break away reducing frontal area and increasing penetration. The jacket looks to be quite stiff (for the velocity) as well.

My Brenneke only has a 22" BBL on it, this brings the muzzle velocity down a little bit, my hand loads are only pushing a 286g partition at 2500fps. I would guess the velocity I get with these factory loads would only be a little better than say a 24" BBL x62 Once they show up in the mail I will chronograph them and report back.
