Bullet Weight Inconsistencies?

[GaryS]

I have that much discrepancy in mine. Maybe I'm not good at casting, or my alloy isn't mixed well (not even sure that is a thing). I load for the heavier bullets and call it good. At the end of the day, 4 grains of bullet weight won't make much difference in function or accuracy from a handgun, in my very new to casting opinion.

Thanks Gary!
I appreciate you taking the time to respond. Hearing that you have the same degree of variance gives me some confidence to move forward.

Hope you have worked through this problem by now, For me, I say a four grain variation is not even close to acceptable. It's possible to make runs of bullets with a fractions of grains variation. To give an honest appraisal it would be necessary to see the bullets.

Casting technique: Possibly, the first place to look is the sprue. The lead is drawn in to fill the mold. Allow the sprue to cool enough to change color. This is where the lead is drawn in to fill out the bullet. The bullet base may have rounded corners. I cast at 750 degrees. To me. when casting bullets everybody stays a newfer. There is always something to learn. Don't give up. Uniformity has all to do with technique.
