We have killed many elk with the 230 OTM from a 300 win with MV of 2775. I don't ever remember one that didn't exit. The last was like 180 yards and the exit was 1 1/4 to 1 1/2". The 230 target is to have a thicker jacket so I would expect even less expansion. We have drove them through shoulders at long distances but onlt because my wind call was off. We always shoot for the crease tight behind the shoulder. This hold gives a much wider kill zone for windage variance. If you get it in the vital zone, ideally tight behind the shoulder a little below center, it will be the fastest kill you can get with any bullet.
Not all bullets act the same in different calibers. The 230 / .308 bullets have been very good for us holding together than some smaller calibers or even the 215's in the 300's.
I guess what I want to say is there is not one set of rules that will tell how a bullet, of the same manufacturer, type, will act in all calibers and weights. One size does not fit all. After many kills with them I have very good confidence in the 230's.
