First things first...
The ballistic experts ( Fletcher and Mead) in this case, do not link two of the eight bullets, or bullet fragments to one of the same bullets recovered during autopsy, or to any of the 5 loose recovered WHOLE BULLET from the main bedroom. Although both Fletcher and Mead are experts neither of them could physically link any of the 25 individual bullets, or pieces of bullet to any one of the recovered 25 cartridge cases, nor might I add, any part of a bullet, to another part of another bullet recovered from the body of Ralph Bamber during autopsy, or any victims bodies during their respective autopsies, or from the scene. But in order to try to make some sort of sense out of the logistical chaos that clearly exists involving the number of bullet wounds to victims, bullets or part bullets recovered from the bodies of victims and at the scene, and the number of recovered bullet cases, you have theorized that in order to account for the existence of a 5th WHOLE BULLET found in the main bedroom, that one part of one of the 8 bullets recovered by the pathologist during autopsy is somehow linked to one of these 5 WHOLE BULLETS recovered separately from inside the main bedroom. Well, the fact of the matter is, that neither ballistic expert nor the pathologist, or even counsel for prosecution or the defence, nor even the trial judge, has ever attempted to suggest that which you have decided must be true. There is no evidence either from the examination of Ralph's body during autopsy, or examination of bullets, or part bullets recovered from Ralph's body, or gathered loosely from inside the bedroom, that two of the wounds were, as you put it caused by two parts of the same bullet, albeit one part of this bullet was recovered from inside his body during autopsy, whilst the other part was recovered from the main bedroom by DC Hammerskey? None of the experts, allege that any of the 8 bullets, or part bullets recovered from Ralph's body during autopsy, could be linked to any other part of a bullet found in his body, or elsewhere, for example, loosely at the scene in the main bedroom?
The bullet weights I have been referring to were published in one of the Manchester McKensie reports on the Bamber case, and weighed, 2.27gram, which does not convert to 40 grain. The chart in question was posted on one of the earlier sites on the internet accompanying one of the Manchester McKensie Reports also posted up about the same time. This chart gave comparison bullet weights for differently manufactured bullets, including many of the types of bullet used in these killings. I do have a copy of the chart and the accompanying Report somewhere amongst the thousands of documents retained by me regarding the case, but I am unable at the moment to lay my hands upon it, due to us moving house a couple of years ago, and all the documents getting mixed up during the move from one house to another. But when I eventually get around to laying my hands on it, I will repost it so that this matter can be cleared up once and for all...
