If you can't find load data for a specific weight bullet.Is the next higher weight ok or do you go lower and what do you start at. I just noticed on some of cast bullets molds, the Load data is not listed anywhere.I know you start lower but don't want to have dangerous rounds.I am still learning . A ground at the range had a reload blow the mag out on his 1911 45. He said it was either a bad case ,undercharge,overcharge or the bullet set back from bad crimp. Just don't want this to happen thanks
