I dunno' if anybody else thinks this way, but it's tough for me to relate Barnes bullets with others when working up a load... meaning that sometimes I'll take a look in a manual, locate a given weight bullet, and use their data for another bullet (given that work up is involved)... but with TSX and TTSX, the charges just don't seem to line up, and sometimes it takes a bunch more or a bunch less powder to get where you want to be (maybe the shanks, or small bearing surfaces?)
Could just be very amateur handloading, as well... grin
