What's the practical difference between them? I thought jhp is more popular in handguns and jsp is more popular in hunting rifles because higher velocity allows simplier bullets to expand reliably but seems like there is quite a lot of handgun jsp ammo.
>>64661826As you said, it's generally a matter of expansion, velocity and penetration. JSPs expand less and thus penetrate more, which is desirable for hunting big game or barrier penetration. This is also true for rifle bullets. They often employ complicated means like bonding, partitioning or choking the core to limit expansion and core seperation and gain penetration. This is just a means to tailor bullet selection to your target.
>>64661848This. Bullets exist in a spectrum. At one end you have bullets that are designed to not expand at all even when striking hard materials like armor, i.e. AP bullets with tungsten or hardened steel cores. Next you have bullets designed not to expand, but they're not tough enough for use against armor, i.e. "Solids" for dangerous game or FMJs. Then you've got various kinds of semi-expanding bullets with lots of different designs--bonded, partition, blah blah blah. Then when you get to the other extreme you have very quick-opening hollowpoints like varmint bullets, and frangibles. Depending on what you were shooting you'd pick a bullet design with the correct amount of expansion.
