the core on the nosler balistic will always come of the jacket and the bullet will pretty much disengrate and turn to dust specialy at close range at high velocities. but the heavier balistic tips are built tougher then light 85gr is for varmits and 100 for game animals and 115.
these bullets are designed to still exspand/come apart at long range and kill game were at exstreme long ranges some hunting bullets will still penetrait but fail to exspand.
i killed a buck at 250ish with my 3006 and 180gr nosler bt shooting almost straight up hill broad side the bullet enterd very low went through a rib hit the inside of the front shoulder blade then down through the leg. i tracked this bullet when skinning and found bullet fragments the entire way.
a bullet i dont shoot deer with any more is the 100gr nosler bt at close range it blows huge holes in deer. at close range the 115 seems much better.
i could talk loads and bullets and how they perform on game all day. this 25 and i have about 11 years together and about that many bucks under our belt not mention dogs and smaller critters.
i didnt even talk about nosler partitions.
or how well i like remington corelokts
i could go on and on
heres a few of whats on the wall
