A very pertinent point Outlook,
I have always wondered about that exact point myself. How did Bamber fire all those bullets, reload at least twice and keeping 5 people inside the house without raising the alarm?
If what you suggest is the case then Bamber MUST have known exactly which rifle he was going to use in order to bring the necessary amount and calibre of ammunition. This would be the rifle he deliberately left in the bathroom in order for it to be within easy reach when he first gained entry to the house via the fanlight on the toilet window.
However, I believe that the fight in the kitchen came about because Bamber ran out of ammunition at a vital time. His plan was almost scuppered by the unexpected resistance that Nevil put up when he realised Jeremy had no bullets in the gun. Unfortuntely Nevil was serverely injured due to the initial onslaught in the master bedroom by Bamber, and was unable to wrench the weapon from Bamber's grip. This is where Bamber proceeded to turn the rifle around and batter Nevil senseless with the stock end - using it as a club. Once Nevil was unconscious Bamber walked over to the kitchen cabinet where their lay the spare box of ammunition. He reloaded and then callously finished his father off. He could well have brought his own ammunition from Bourtree Cottage with him to the murder scene and used it. I do find it somewhat difficult to believe that Sheila shot herself with the last bullet in the gun. That it just too much of a coincidence for it to be plausible. Isnt it more likely that the killer used his own ammunition when the magazine was found to be empty? He simply added another to the empty rifle, becuase he knew that's all he'd need. So your idea certainly makes a lot of sense Lookout. It is an added dimension and one I havent come across previously.
Thanks for the post Outlook

. Great thinking!
