Nearly all the casings associated with the initial assault on Nevill and June's murder were found in their bedroom indicating the shooter was either in that bedroom or just inside the door. There is no other logical reason why those casings were there. Their position on the bed and on the floor are an extremely good indicator of what took place.
The trajectory arguments are not valid since Nevill's position relative to the gunman at any given point in time cannot be determined. If someone pointed a rifle at you Holly and threatened to fire it what angle would you be to them?
Undoubtedly the shooter was shocked to find that his victims were not rats and that one or two bullets from a .22 rifle were totally indequate in putting down an adult human being. He ran out of bullets quickly and had to retreat downstairs to get more ammunition closely followed by Nevill who stumbled against the stairs leaving a trace of blood on the wall. A fight ensued in the kitchen as the shooter didn't have enough time to reload before Nevill got to him. This fight was Bamber's undoing.
Team Bamber have never been able to come up with any scenario which places Sheila in that fight.
Based on trial testimony from Dr Vanezis and Malcolm Fletcher we cannot even be sure if June sustained 5 or 6 gsw's to her body. I am inclined to think she sustained 6 gsw's to her body and 2 gsw's to her head: 7 entered, 3 exited and 1 gsw was a graze only wound. The graze only wound represented by bullet DRH/5. This would then account for the 8 casings found around June's side of the bed and the 4 bullets: DRH/35 x 2, DRH/9 and DRH/5.
The other four casings: DRH: 3, 4, 13 and 14 do not imo lend to NB being shot whilst in bed or in the process of getting out of.
The track of the bullet [upon entry to the body] determines the position of the gun. The pathologist in the Bain case explains @ 8 mins in:
"Allows you to reconstruct the direction that the barrel was pointing in. Because that is one of the things you can do in the reconstruction of gunshot wounds unless there's some intervening target. You line up the track of the bullet with the barrel of the gun."

https://en.wikipedia.org/wiki/External_ballisticsDr Vanezis makes clear the trajectories of NB's gsw's to his face were both some 20 degrees below the horizontal. This imo is one of the most important pieces of evidence from soc coupled with the fact he also states the trajectories to NB's shoulder and elbow/chest gsw's were also downwards.

https://www.youtube.com/watch?v=R5JDhi4URdsThe experts incl lawyers and judge at JB's trial were imo complete numpties and/or just bone idle and couldn't be a***d. We now have trial tanscripts from Dr Vanezis and Malcolm Fletcher and it is clear this aspect of the case was not even touched on at trial.
Trajectory analysis of gsw's is a sound forensic technique which should have been used at JB's trial to establish the relative postions of shooter and victim:
https://www.ncbi.nlm.nih.gov/labs/articles/28089298/The trajectories imo throw serious doubt of the prosecution case that JB entered his parents bedroom and opened fire. It all points to SC already in the bedroom shooting June with NB shot on the landing and stairs as he approached and then retreated. The good news is that soc experts should still be able to prove this one way or another by assessing the layout of WHF, soc images and autopsy report and photos.
