Those were the last 6 lots acerages withing the lot... What would you exxpect the extreme spread to be within any of the above lots... It's interesting to see lot to lot variation in weight, how about the variations within the lot.
Say you cut 25,000 cores for 25,000 jackets you have ordered to make 116's, but only 15,000 jackets come in and you are left with 10,000 cores for the next lot witch may vary in weight from the last lot you recieved... now do you have 116.4 bullets? or whatever? Is that why we see the difference in weights from what is advertized and what we get?

Paul, this is pretty much, "IT" .
If one sits around waiting for the next jacket LOT,
unrecoverable TIME is running under the bridge and the hapless custom bullet maker falls further behind: squirting cores for an "average" weight enlarges the bottle-neck somewhat. Occasionally, even with [what an accountant considers] a HUGE [jacket] inventory turns out to be, "not enough"!
Within a jacket LOT, the weight range is normally well within the, "
*Maximum weight variation 0.2 Gr. within LOT"; you'd have to invest a LOT of time to find a full 0.2 Gr. range. When I receive jackets, I open every other case (four buckets per case), open two of the buckets, weigh and 'spin' (for wall run-out/uniformity) 40-50 jackets from each bucket . . . then, during the process of making bullets, occasionally do a random check on another 50 jackets - whitin an acceptable LOT, I have yet to find weight variation to be an issue.

Note: *taken from a SPIVECO jacket print (1.00" thirty caliber), sent to me, upon request, from SPIVECO, about 1995 . . . the SPECs may have changed slightly since then, but not appreciably. SPIVECO was the original manufacturer of J4 jackets and pruchaser of BERGER BULLETS, both of which were later acquired by CARAN. Though now 'consolidated', I believe that both BERGER BULLETS/J4 are subsidiaries of CARAN.
