I have recently started reloading again. When purchasing supplies I looked at some new books and found a big discrepincy in the amount of powder used on some loads I used to reload. I found that in the Speer reloading manual I have always used that using Blue Dot, a 240 grain JHP bullet, magnum primers, that the recommended load ranged from 16.2 -17 grains. The new books I was looking at recommended 11.2-12 grains. Anybody have any insight as to what's up? I went to a local gun shop and didn't get a whole lot of satisfaction about why the big difference in the loads using the same powder. I did change to H110 for my latest batch and it worked very well, and wasn't quite as dirty as the Blue Dot.
