As for bullets that supposedly don't expand at all until they have passed through a few inches of tissue,and then suddenly expand violently in the vitals,it just doesn't happen that way.There is no magic bullet that passes through the hide and ribs or shoulders,without any expansion,then suddenly goes off like a bomb when it reaches the vitals.
Yes and no. The Berger is designed with a very thick jacket in the nose to aid in delaying expansion and once expansion begins, they fragment very quickly. Obviously, velocity plays a huge role in when expansion begins and how rapid it is but the design of the Berger is to provide initial penetration with minimal expansion and then very violent expansion after that. While in theory the energy dump sounds impressive, the fact that the bullet is rapidly shedding weight does limit the energy the deeper it penetrates where bullets like the TSX retain weight well and expand well, offering an impressive temporary wound channel without fragmentation.
