All I can say is Rich M. was explaining that at the PA open last year and also talking about how they control the weight with varying the lead core cuts by weighing bullets every so many rounds.
As for the cause being buying seconds. Not hardly and only an idiot would buy comp bullets in an opened box at a gun show. I was buying directly from Midway and others and they were unopened boxes. I quit buying Sierras for that reason 3-4 years ago and went to Clinch Rivers and BIBs for comp.
I was running them on Stoney points and the Buhay ogive checker so I know exactly what they were measuring.
Now if anyone doubts that is a problem go to David Tubbs website and see what tool he is selling. (Buhay ogive checker) Wanna guess what brand bullets he normally shot? Guess he was buying culls at the gun show too.
I am quite sure Sierra does not want to talk about it but enough shooters were sure running into problems with them.
a little off the subject but was wondering if anyone knows if the same lead is used for match kings and hunting bullets? i heard once the match bullets used a softer lead but can't remember the source.anybody know for sure?

BartB, since jackets are slightly tapered on the inside, how does "about 3/8" inside the jacket" provide a repeatable basis for comparison?
[/ QUOTE ]There was a fixed flange about 3/8ths of an inch back from the ball's maximum diameter point. Jacket mouths stopped at that point so the same place back from the mouth on all the jackets would be measured. As long as that flange stayed at the same place relative to the ball, the same point on the jacket would be measured. The exact distance didn't matter; .375, .362, or exactly one centimeter (0.039369458748681123131919182375081-inch); repeatability was very good indeed.

[/ QUOTE ]Sierra used to use pure lead in their match bullet cores. Hunting bullets had lead alloy cores with 6%/4% antimony/tin, 6%, 3% or 1.5% antimony depending on the best combination of accuracy and expansion required. They're probably still using the same stuff.
