[QUOTE="nralifer, post: 2964704, member: 94556"] There are a couple of things that you are ignoring. The most obvious is the effect of the tip, whose material is substantially less dense than copper, making the copper portion of the bullet the predominant determining factor in stability. The second is that AB has not extensively tested our Bulldozer hunting bullets for terminal performance or even accuracy. We now have several customers who have shot 30 or more animals with our bullets and have noted over 90+% clean one shot kills, way above what they were achieving with other bullets. The SG of 2 applies to ELR situations where the bullet transitions to subsonic speeds usually at 2400-2600 yards down range. Additionally very high impact velocities can cause very weird effects not seen with lower impact speeds. Lastly, with petaling the bullet length immediately becomes much shorter which helps with stability in denser flesh. In addition, any asymmetry created after petaling will steer the bullet due to the spin imparted to the bullet by the rifling. I remind people that experts that don't hunt with our bullets but comment indirectly about them by lumping them into the mono category really don’t know what they are talking about because they totally lack experience.
