I recently read in the attached that the printed max load value of #9 is 14.9gr for a 180gr bullet in 10mm, but was an error. It should be 14.2gr max. Well I had previously worked up a load to 14.9gr (and even a bit higher) and reached a velocity of just over 1320fps out of my M610. I used a 180gr Brazos Precision FP NLG cast PC bullet, and I had no issues, no sticky cases, but I don't measure the case heads. Have anyone ever come across this before? Makes me wonder if some load data publishers are intentionally publishing light loads to CYA.
