Well,
just finished with the bullets.
From 135 bullets I rejected 33 and have some problems closing the mold (some lead between) and I have 24 oversice bullets that I will try someday.
After weighting each one I get the following:

C1 C2
458/459 6 7
458/460 7 10
460/461 13 18
461/462 10 4
462/463 1 1
463/464 1
38 40
Rejected 18 15
Oversice 11 13
67 68

C2 is the cavity closer to the handles and C1 the other cavity. For what I see there is no much difference between cavities.
Bullets are heavier than expected, according to Lee it is a 440 gn mold.
How much difference between heavier and lighter bullets do you recommend?
I would prefer to keep the bullets between 458 and 462 gn, 75 bullets.
Thank for the advises.
I will try again soon using an aluminum block to cool the mold if its necessary.
Thank
Martin

PS: can not edit the table right, hope you can underestand it, first mumber is weight range, then bullets from cavity one and then from cavity two.
