Just that alone can and will cause very different behavior.
People generally believe, and companies keep repeating- that “the tip drives back into the bullet causing expansion”. That is not what happens in almost all cases and it is clearly seen in gel.
Almost always the tip squishes out of the bullet soon after impact explaining the open cavity, or it breaks off creating a larger frontal diameter.
Aluminum/metal tips do neither- if the bullets upset it’s generally because the bullet started to yaw or starting to destabilized, then the tip get pressure on the side and it tears out of the jacket causing massive fragmentation. Other times it remains point first and exhibits basically no upset.
