I went down to my local gun store today and bought a box of Sierra 197 grain match kings. I'm going to shoot them out of my 28 Nosler which has a 1-8 twist barrel. I called Sierra and they said with the tip being closed very tight they weren't sure if the would open up on game animals. So my question is has anyone tried these on and animal yet and how did they perform? I'm going to try testing them on dry newspaper bundles over the next few weeks and see what kind results I get. Spring bears are open where I live now so If they work on news paper then I will take them out bear hunting at the end of the month.
