5.8x21mm Chinese bullet question

Hi guys,

I have three bullets for the 5.8x21mm Chinese pistol cartridge shown in the picture. While the two on the left are identical and have a shape as found in pictures on the internet, the bullet on the right features a tip with a larger radius and an ogive shape which appears to progress at a slower rate.

My question is whether the bullet on the right is a special variant such as for a subsonic version of the cartridge or whether it is something else.

Thank you


Are these complete projectiles or only jackets?
Did you weigh them?

They are complete projectiles. I do not have scales to weigh but here are photos of the base.



Thank you
