get a recent copy of the book "cartridges of the world"
https://www.amazon.com/Cartridges-W...+the+world&qid=1634661752&sr=8-1

its very interesting to read about all the cartridges that have come, gone, stayed, etc...

when lead meets venison it really doesn't matter very much what the text on the headstamp says....

all these new cartridges are not designed to get a bullet from the hunter's barrel to the deer's vitals faster, they are designed to get money from the hunter's wallet to the ammo/gun company's bank account faster!
