They look like they continue all around the bullet...


I suspect that slug came out of a jacket, the jacket being the impressing force which transferred the land impressions to the core.


I think the land engravings on the bullet are too sharp to have been transferred through a jacket. Under magnification there are numerous full-length straitions that I do not think would show the same way if they had been in a jacket. I stick with the notion the bullet was a semi-wadcutter design with a hard shoulder and a solid crimp.

Mark Begich, Joaquin Jackson, and Heller resistance... Three huge reasons to worry about the NRA.
