weights of fragments are useless in trying to assess whether a round is high velocity or not or whether it is solid.
The examination needs to concern the physical looks of the bullet to figure out if it is a hollow point or solid and unless the nose is intact you can't really tell the difference because other than the nose they are identical. You get the velocity by identifying the cartridge in question. If one wants to try making assessments as to these issues then they need to have access to the bullets or adequate photos or descriptions from someone who examined them and then point out what specific things establish what. Just making a chart up without explaining in detail the evidence being relied upon to reach conclusions accomplishes nothing.
Fletcher had the bullets, he physically examined each one, he described them for what each bullet was, the police accepted his descriptions, the CPS accepted his descriptions, the defence ballistic expert Major Mead accepted his descriptions, theses 25 bullets were what they were, and nothing you or I or anybody for that matter can change the reality of the situation - these were bullets from different batches or types of .22 ammunition, some .22LR bullets, some .22 bullets, and one just recorded as a bullet. FACTUS, CAPPUT, END OF, there is no other explanation for it, no other interpretation that any body can come up with, ZILCH. But if you want to add or alter what Fletcher has said then you go a head, but it still won't alter the fact that in that collection of bullets, there never was just one type of .22 ammunition, or bullet...
