Are there any rules of thumb with brinell hardness of cast lead alloys and velocity?
If i could guess it would be something like:
(Based on manufacturer's recommendations)
BH 12- 900fps
BH 15- 1100fps
BH 18 - 1300fps
BH 22- 1500fps
Obviously bullet "fit" is a big factor in wheelguns too.
Just looking for opinions. Trying to learn more on the subject.
I have had several loadings over the years that are will randomly lead up the barrel, and others not.
I personally load 357 mag and 44 magnum and use 158 and 240 gr lead bullets with brinell hardnesses of 15-18
