So, here are two data points for you. I order powder every quarter, last time I ordered just over 1200lbs and the lot code for the powder was 2742. The previous quarter it was 2740. I am small potatoes, so two lot code revs within 3 months and if there are 100 guys like me ordering every quarter, that means a single lot code covers a lot of ground. Last pallet of primers I bought were all the same lot code, it was just shy of 500k on there. However, I rarely buy that many at a pop but I typically see the same lot across 100-250k. I'm one of many buying so the primer lots are probably fairly large as well.
