Actually Nick you could use the same argument against JB.
Hi Grahame, my point being;
JB had to use the Anschutz for continuity, as that is how JB’s plan started - with him using it (allegedly) in an attempt to shoot those rabbits (without tele sights, and the moderator fitted).I might add that JB setting the scene with a shotgun (and leaving that conveniently out on the settle) was more risky, as popping out to shoot the rabbits at distance with a shot gun was probably less believable than the Anschutz.
I also believe JB felt that to kill all in a more efficient manner was to use the Anschutz (multi shot with spare magazines), than using a shotgun, having two initial loud shots, followed by breaking the barrel, inserting two more cartridges etc. I believe JB saw the Anschutz as a better choice – it’s just that he underestimated the strength of his father and had to resort to fighting him before re-loading (with a spare mag?) and killing him.
If Sheila had used bullets from the work surface I would have expected (in her anxious state) for some them have been scattered on the kitchen floor, and as far as I am aware non were.
No, if any bullets were taken for reloading purposes from the kitchen surface they were taken quite carefully.
