The lyman 44 (1967) shows some pretty heavy maximum loads for 32 S&W long, like 4.3 grains of unique for a 93 grain cast bullet and 3.5 gr for 115 grain cast bullet.
Meanwhile the Lyman 48 (2002) manual shows a maximum of only 2.8 gr of unique for a 100 gr jacketed bullet. It doesn't appear to be a change in load because of jacketed vs lead, beacuse the lee manual (2003) agrees with the lyman manual, and species a max of 2.7 gr of unique for a 98 grain cast bullet
So how trustworthy are these older loading books?
I know Sharpe's 1937 book even goes to suggest 4.3 gr of unique as the maximum for a 98 grain cast bullet, but I'm not sure if the formula of unique was different back in the 1930's.
