Not quite. Its one of the BT's with a VERY heavy jacket, comprising around 2/3 of the total bullet weight. Generally these models retain at least 60% of their original weight, even if they lose the lead core. This is apparently what baffles some hunters, because they've long believed any bullet that loses won't penetrate deeply.
But all the "hunting" BT's (as opposed to varmint models) have far heavier jackets than other cup-and-core bullets. Those I've recovered retain around 50% of their weight, give or take 10%--about like the Hornady Interlocks I've recovered.
