Hi all!
Tonight I cast some Lee C309-170 COWW for 30-30 and I observed something odd while doing some quality control..
I cast 177 total bullets, tossed 18 for defects or out of weight tolerance so I ended up with 56 bullets that were within .5gr of 177.1 grains and 103 bullets that were within .5gr of 176.8 grains.
The two sets of good bullets looked really nice and were mostly within .2 or .3 tenths of each other but I thought it was very odd that the two different weights were so far apart and could only surmise that the Lee 2 cavity mold was throwing two different bullets weights but I also find it odd that the number of 176.8 gr bullets outnumbered the 177.1 grain bullets by almost double.
It's been a couple of years since I cast and even then I don't have much experience casting, I kept the lead in the Lee 20# pot between 750-780° and the castings looked nice I thought.
Would that be the mold throwing two different weights you think? I just think it's odd that even then one set outnumbers the other set by almost double.
