Alliant Blue Dot
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!
1. Blue Dot fills up the 357 Sig
case nicely.
2. It doesn't measure as well as I'd like but it does OK.
3. If you like a large bright flash, then Blue Dot is a
lot of fun.
Steyr M357 with a 4" standard barrel
