View Full Version : Bullet weight consistency

February 2, 2010, 07:16 PM
I am casting 200 gr .452 LSWC with a lee 2 hole mold. I was wondering what kind of consistencies you are getting?

I weighed about 10 bullets and the range was from 193 - 195 grains. This variation seems ok to me.


That'll Do

When casting with my RCBS 44-250-K 2 cavity mold, my bullets range between 258gr and 260gr. I use a modified wheel weight alloy (tin and antimony added).

Most of my molds only vary weights by a couple of grains, at most.

That's about par for the course for me... 1 to 2, sometimes 3 grains in variation within a given casting session.

I work on the 3% rule& your in that range .
I try to keep everything the same temp , preheat the mold & the little 10#er holds temp alot better since I installed a new thermostat!! & with the isotope alloy I have I run the temp at 775f.

That small batch in the pic thread ran +- .3 grs. from 162 grs. for a 357446 bullet, I was very happy & runnin at 10.5bhn & dropped from the mold at 360" , I have very happy GP100s:D
