Just got through casting, powder coating, and sizing 45 lb into 200 gr .45 RNFP
got to thinking (a lot of time for thinking when sizing 45 lbs of bullets): is the final diameter different depending if you size when bullets are warm vs. completely cooled?
My thinking is the warm ones will be sized to .451 and then drop down (contract) a few thousandths once cool while . . .
the already cooled ones will remain at .451.
I find the freshly PC ones size more easily than the fully cooled ones (not a biggie either way--just an observation) + I can size them while waiting for the next batch to bake
both shoot well with no differences I can see
Just curious . . .
