Not to muddy up sdporter’s post on what’s wrong.
Casted a box for Stephen Tucker (WR whitetail) and thought I’d share how bullets increase in weight as temp rises.
These are 540gr 45cal bullets Pure lead with a touch of tin, so the 5gr difference from 541-545gr can be visibly seen in the lighter bullets in form of wrinkles.
I let the pot heat to 700 (blue film on top), let my AL mold heat up close to the burner, started casting.
I thru a few back in as I can tell if the mold is hot as my HP pin can be removed easily, like normal I would say.
A box of 50, can be cast in under 30min.
After they cooled, I weighted the 1st half (photo) 541-544gr, then added the other 1/2 total - you can see I added a row to the right/heaviest and it has the most.
Final temp when done was just over 800 (thin film starts to turn yellow/gold), good bullets...
You can see from the photo, if I’d kept casting another 50+ the bullets would have continued to be heavy/uniform in weight.
1st half, 1gr rows
Added 2nd half - all bullets casted 541-545gr
Left early 700 degree bullet, Right last bullet (800) heaviest.
In matches, I’ll group bullets into 1gr increments - honestly I can’t tell a difference even with a few gr of weight difference.
