If your close to Sedalia MO. go to the Sierra plant ... they sell "seconds", it used to be 1/3 of what the boxed bullets sold for.
When I was shooting a lot, I'd make a 2 hour pilgrimage there every year & buy 5K of 69 HPBTM 223's & 5K of 168 HPBTM 308's ... Then for the next 2-3 weeks I'd spend evenings watching TV, sorting & weighing into groups + or - .3 grains ... The few that had malformed jackets I'd use to warm the barrel, very few were ever tossed out.
