Follower plate marks are not often observed or recognized. It doesn't establish anything. Lip marks are readily recognizable and were mentioned to refute the notion the ammo supply was brand new untouched- some of the rounds had been loaded previously. There is not a reason to try to discern what the most subtle of marks are because it has no bearing in tying a bullet to a particular weapon that is what matters most. You spend all your time on conspiracy crap that proves nothing instead of what actually matters.
Follower plate marks are important, and do not appear on every round loaded into an ammunition magazine, unless every round is individually loaded into the magazine and then fired. In the circumstances of this case, it was very important to identify any bullet case with a follower plate mark upon it, because of the prosecution argument which they presented to the jury that there had only been one rifle used in the shootings, and that an additional 14 /15 rounds loaded into the same ammunition magazine in order for all of the 25 rounds to have been fired during the incident, and the fact that the hand swab evidence taken from Sheila showed insufficient lead deposit readings, for Sheila to have been the shooter. In the circumstances of this case, identifying at least one bullet case found at the scene with a follower plate mark upon was necessary to at least give some credence to the suggestion that the magazine belonging to the anshuzt rifle had been reloaded during the shootings. The fact that not one of the 25 bullet cases had a follower plate mark upon them, indicates to me that the batch of crime scene bulet cases was tampered with by police, in the knowlege of the ballistic expert, Malcolm Fletcher...
A 25th bullet case was added to the crime scene batch of bullet cases, to create a false impression that 25 shots had been fired, when only 24 had been fired, including the non fatal shot across Sheila's neck, from a police issue weapon - adding a 25th bullet case to the batch of crime scene ammunition was a blunder of great magditude, police and the ballistic expert confused themselves by adding the 25th bullet case, when only 23 rounds were fired through family owned .22 weapons, during the incident unfolding inside whf, the 24th round having been fired through a .22 police issue weapon...
