@ Luke, I' ve done it both ways, treating people with dignity and tact is not politics.It's just the right way to treat people. I know the difference and have no trouble disagreeing when there is principle or conscience involved.
When people are willing to talk in a civil manner, things make progress. Don't confuse kindness with weakness.
As to the extra weight, I don't know. Don't different alloys vary a bit ? I bought a ten pounds lead ingot, I don't know it's composition, other than hard.
My scale is calibrated, and recalibrated, at any rate, it's easier to find formulas for 158 grain bullets, I'll take it. 😉
What might be a good all around powder for .38- .357 in the plus P .38 to mid powered .357 loads ? I' m not looking for anything fire breathing .
I promise to stay in manufacturer specs.
