Thank you Mike. It does beg the question Do bullets become heavy when fired? I will do a bit of googling....the only other answer of course, is that different bullets were used...?
Yeah, I was wrong in suggesting the manufacturers bullet weight specification was 2.26gram, because it is 2.27gram...
I'll let you off the 0.01g, if you tell me why you think some are heavier
Were they hollow or solid bullets?
The ballistic experts, Malcom Fletcher, and D. Taylor, did not differentiate the type of .22 bullets to that / this extent - see general examination records for confirmation of this...Please visit:-(1) - http://jeremybamberforum.co.uk/index.php/topic,2506.0.html
Mike I have a strong feeling that these are either exit bullets or missed bullets. The bullets have to weigh lighter, because it loses the outer brass case...Fletcher can't be sure that two of the bullets came from wounds....if this is the case then we might have bullets that missed their target...at close range...
Isn't mike talking about the lead bit, rather than the whole thing including the case? Any of the other bullets could have also originally weighed 2.42 as well I suppose. Not sure where any of this gets us!
Eley .22LR subsonic hollow point ammunition weighed in at 2.27 grams according to the manufacturers weight specification chart, yet five of the 25 crime scene bullets weighed too much to have originated from such a batch, and another seven weighed to little (all described as being whole in nature). That is a total of 12 bullets out of 25 that do not fit the manufacturers weight specification for Eley .22LR subsonic ammunition - which in turn leaves around 13 bullets which could have originated from the relevant batch...
Bullet PV/20 is one of the 12 bullets which falls into the category that could not have originated from the batch of Eley .22LR subsonic hollow point ammunition, because it was too light which effects the statistics because the original (PV/20) was substituted making the ratio 11 / 14...This is where the analysis starts to get very interesting...
If anyone is really interested, check the type of bullets mentioned in each of the individual general examination records, and you will see that none of them are referred to as .22 LR subsonic hollow point rounds, or bullets, or whatever...(1) - http://jeremybamberforum.co.uk/index.php/topic,2506.0.html
A solid whole bullet weighs in at about 2.50 which would make more sense....than a 2.27 hollow one. Maybe some were solid...Sad about Paula Radcliffe Anther hankie wet through...aww
