I'm wondering if it's just me or is anyone else not able to obtain the velocities listed in loading manuals without more grains of powder than are indicated? Stated another way, whenever I use a certain amount of powder, my velocity is anywhere from 100 to 300 or more feet per second slower than what is indicated in the manual. I've noticed this with both of the rifle rounds I load (30-06 and 22-250) from three different bullet makers and their respective manuals: Sierra, Barnes and Hornady. To date, I've simply used more powder to get the velocity I'm looking for, all the while watching for signs of too hot a load. So, are the manuals wrong or am I doing something wrong?
