Alliant Power Pistol
Disclaimer: All of the following powder
charges were taken from reloading manuals produced by gun powder companies or
other reloading manuals that may vary in powder charges greatly. Various
components combined, make all the difference in the world. I am not responsible
for your actions. Always refer to official reloading manuals when reloading. As
usual, I must say that this information is what works for me. Use your own
common sense. You are responsible for your own actions!

I had an older set of reloaded ammo using
Rainier Plated Bullets. I did not have a cannelure
groove on the bullets but I did have a tight crimp that cut a crimp ring into
the bullets. So here is another set of data using Power Pistol:
