There are many variables and bullet development continues. Note that premium handgun bullets are bonded with no separation [which is in effect fragmentation] .Lead alloy of the core varies from pure lead to 1.5% Sb to 3% Sb IIRC .Then there are the all copper types , DPX, TSX . I want no fragmentation ,no jacket separation , full penetration [especially for hunting]. The round must be able to penetrate into the vitals to do a good job.
