[QUOTE="bigngreen, post: 1664745, member: 13632"] Open tip match bullets open by hydraulic action inside the tip popping it open many times actually from the top of the lead to the tip then rolling back, this takes time to create the case conditions to open and that's why we see the delay, if one blows up or opens on the hide it's because the jacket has been stressed by either a rough barrel or to much launch velocity. Being that they open by hydraulics the cavity in the nose is an important feature to look at as well as jacket thickness. Look at the 215 Berger, heavy jacket but opens absalutely perfect and consistent every time, the cavity is the key. You can take the Cauterrucio bullet which ran a pretty open cavity but was a little thinner jacket, they were explosive but still internally not on the hide, the 155 was almost identical to the new 156 Berger but the Berger had a little thicker jacket which I expect will be an amazing bullet to hunt with.
