Found some of these today and don't remember where I got them. The pointed ones are in WW brass and must be a kind of AP load. The round ones with the 2-tone nose are in geco brass. May be similar to Glasers?
I believe the pointed ones on the right are Winchester loads. We carried a box of 50 in the glove compartment of our patrol cars back in the day. They were designed to penetrate auto bodies and engine blocks. As I recall the boxes were yellow. We used them at road blocks. If I recall correctly the bullets are solid or mostly copper in the nose.
