I’m not sure the metal alloy but the construction of the Peregrine with the metallic solid tip for expansion vs a plastic tip as well as the multiple shank grooves is different from the TTSX. Maybe better maybe worse?
I will note that knocking a bullet out with an impact puller forced the metal tip in enough to start expansion. I shot it this morning and it sounded good hitting the steel at 20o yards!
Here is a picture of the one bullet that was recovered from the Kudu earlier this year and the bullet that came out of the impact puller, you can see the tip driven in and the expansion already beginning. We are getting off topic but I believe lighter monometal bullets can be very effective.
