A nice guy on another board plugged in my 9mm numbers to QuickLoads software and came back with some rather disturbing figures. Now I'm using a Lee TC 124gr boolit, 4.0gr 231 and 1.045oal due to chambering issues with the design. He plugged those in, came back with an overpressure charge over 40k psi. Thing is, I was told from the beginning to load 10% below max listed in my Lyman manual and what is on the Hodgdon site, which is 4.4. The listed OAL is longer, so I dropped it accordingly...but not enough? I have no signs of overpressure...flattened primers, cracked cases, nothing. It ejects pretty far and feels a bit warm, but thats about it. So what, should I be loading to 3.5gr now? Wanna kill these ads? We can help!
