I know that's why it does not get absorbed .
I don't think anyone has explained the missing bullets - its not a matter of Jeremys story not adding up . It would appear that whoever the killer was there were 5 bullets used that were not from the box of 50 - so they must have come from somewhere else . The fact is we don't know that Neville did not put the gun away and the killer took some ammunition from the cupboard when they got the gun . But what I am trying to say is in would help if the casings were DNA tested .
Jeremy after all never said the 25 bullets came from the box in the kitchen did he?
He just explained what he did before he left the farm.
It seems pretty clear to me, that in a 'Jeremy is guilty' scenario, Jeremy accessed the gun cupboard.
It would be likely that he retrieved the rifle, moderator and ammunition from the gun cupboard, before later returning the moderator.
The ammunition on the counter could have been placed there after everybody was murdered, hence the blood on the counter near the bullets.
Therefore the bullets on the counter and the bullets used don't need to add up to a whole box.
It's often been suggested that Jeremy chased Neville downstairs to the kitchen, I wonder if we've got it back to front and it was Neville chasing after JB when he had run out of bullets?
