A comparison of three recovered bullets that may lend some insight into how bullets of different construction perform.Below are the 180 gr ballistic tip and 180gr tsx out of my 300 ultramag,and a 200gr partition out of my 8mmremmag.The ballistic tip retained a large portion of it's core and retained 62% of it's weight after penetrating both shoulders on a bull elk.The partition shed the entire front core and retained 66% of it's weight after a lung shot that broke one shoulder on a moose.The tsx retained all of it's petals and retained 100% of it's weight after destroying a section of elk spine.As far as frontal area is concerned,all three are similar.(remember that the partition is a slightly larger caliber).
