Of course they were considered - unless you are suggesting they were all asleep? 
As I said before, we cannot know what the jury thought of any particular given argument, all we know is that they considered them all and came to a verdict.
The jury aren't scientists, they are not fully trained in forensics, I doubt half the time, the jury understood what was presented to them.
It is just not a case of whether they considered or dismissed the fact the the 10th bullet was hard to load or not....The argument is from my point of view is that they might have also considered that the magazine would have not necessarily been loaded with 10 bullets and she might have washed her hands after loading....it is as simple as that, and anyone would have to consider it....for it is possible....There are two sides here...I can see both......and, to me it is possible, therefore it all becomes meaningless.
