Hey! I may be ignorant, but I had this much figured out!
However. Yes, there is always a however with me... I do not always have access to a range where I can shoot under windless circumstances AND with sufficient light (read: no, I do not often have access to an indoor 50m range). It would be nice to be able to not even try a batch if there is a large weight variation.
If I would only know what you guys consider a weight variation that is acceptable.
