You seem to think that if you just refuse to admit you are wrong that such will suffice, it doesn't.
For the 5th time he called the test bullets (which he got from WHF) subsonic hollow points in his statement then said the casings and bullets used to kill the victims were the same type. I already pointed this out to you the other day. Saying "same type" means he determined they were Eley subsonic hollow points.

You are deliberately ignoring the now known facts...
Fletcher took part in unreported test firing of the anshuzt rifle, silencer and Eley control ammunition prior to, or on the 12th September 1985. His signature is present upon several 'GENERAL EXAMINATION RECORDS' pertaining to the examination and test comparisons between specific cartridge cases (Marked with 'E') and control ammunition fired via rifle (18), on dates between the 12th and the 19th September 1985. Fletcher clearly had access to test fired rounds, fired in rifle (18), long before he came around to performing his 'OFFICIAL TEST FIRE' of the same, which he states took place between the 20th September, and the 2nd October 1985. Now, why have a separate test fire of the anshuzt rifle and Eley control ammunition (before, or on the 12th September 1985), and a separate test fire of the same rifle and Eley control ammunition, and deny ever having carried out, taken part in, or known about the earlier test fire of the rifle, with Eley control ammunition?
Lets get the facts straight, prior to Fletcher carrying out the so called 'OFFICIAL' test fire of the rifle and Eley control ammunition (between 20th September and 2nd October 1985) Fletcher makes the bold statement that prior to these 'OFFICIAL' tests being undertaken, that he did not know when the rifle had last been fired, but clearly he did. His signature appears on several lab' records which state that various cartridge cases were compared against test fired rounds in the rifle, in order for comparison tests to have been carried out on 12th, 13th, 18th and 19th September 1985 - so Fletcher lied, he lied because he knows the purpose of having had two separate test fires of the rifle and Eley control ammunition. The sole purpose of the original unreported test fire of rifle and Eley control ammunition was chiefly for substitution purposes, so that other manufacturers cartridge cases could be extracted from the batch of crime scene ammunition, replaced by test fired Eley ammunition, so that by the time the 'OFFICIAL' test fire gets under way, from 20th September 1985, the substituted cartridge cases in the crime scene batch are all Eley ammunition. So, Fletcher does another test fire of the rifle between 20th September 1985 and 2nd October 1985, and uses the test fired Eley control ammunition, in comparison tests with various cartridge cases as part of the 'REVISED' batch of cartridge cases, thus allowing him to conclude that the individual cartridge cases subject of the individual Lab' reports, was loaded into the gun and fired from it...
That is all well and good...
My point is this, If the original 14 cartridge cases had not in part been swapped over with Eley ammunition after the 'UNREPORTED TEST FIRE', and there had been no earlier test fire prior to the 20th September 1985, it would not have been possible to match all 25 bullet cases to rifle (18), nor would it have been possible to declare that all 25 bullets had come from the same batch. What I am saying, is that there had to be the earlier unreported test fire of rifle and Eley control ammunition, so that the batch of crime scene ammunition, as of and from the 19th September 1985, was available to be compared against other Eley control ammunition officially test fired from the 20th September 1985, onward...
You do not have two different test fires of the same gun using Eley ammunition, for no reason at all, and then seek to hide for the fact that two such test firings had occurred, not only one...
