Load differences in newer manual - 02/02/23
working on idea for making some new 357 Magnum loads some in rifle some in pistol. long story short :
I have four different editions of Hornady manuals 3, 6, 9 and 10.
6, 9 and 10 have identical data for. 357;
if the old #3: has much different data most of it is significantly higher powder charges of the same powder.
now is that because powder formulas change through that time period 3 to 6 powders changed , bullet anatomy changed or lawyers changed?
