From the outset, let's establish that there is a difference between meplat trimming and meplat tipping. The first process provides uniformity to the meplat making for a more consistent BC. Bullet tipping reduces the size of the meplat, or thickness of the jacket at the nose, as well as increasing angle at the nose. Trimming reduces the BC ever so slightly, while tipping increases BC slightly. My question us this: Does tipping the bullet have a negative impact on the terminal performance of the bullet? Intuitively, I would think that tipping would make it more difficult for the hollow point to open up? Or perhaps just delay expansion a little longer? Did a couple of searches, but couldn't find much on changes in terminal performance.
