Bought a Ohaus bullet mold for 250 grain Keith SWC .44 cal bullets.
Using range lead that was mostly 80%hard cast of an unknown hardness
And 20% jacked bullets.
My bullets average 263 grains.
I know the the percentage of lead in the mix has an effect of the weight.
So I cast a few pure lead bullets ,and they came out at 266 grains.
My question is..
Is this bullet mold something other than 250 grains.
Or is it just my lead mix that is causing the difference of advertised weight compared to actual weight of bullet?
