So, I recently loaded a bunch of 155gr plated bullets in line with the Speer and Hornady manuals for their 155 gr HP bullets with 8.6 gr of Power Pistol. Those loads are now waiting for me to install and master my new Hornady collet bullet puller. They were screaming along at over 1300fps. So the curiosity and too much time (after the Honey Do list was done for the day) kicked in. I decided to see how the three manuals I have compared. I plotted each with just their data and got an equation. I then used that equation to generate data for the all the data point and plotted it. The chart is attached. The book starting and max loads are:
Hornady
5.8 gr 1000 fps
8.9 gr 1250 fps
Speer
8.0 gr 1112 fps
9.0 gr 1213 fps
Lyman
7.o gr 942 fps
7.8 gr 1082 fps
Any comments, like on the difference at a given load? Before anyone gives me a hard time about my load know that those loads REALLY put a hurting on the bowling pins!
I'm just looking to see what if anything those far smarter than I have to say.
