Alliant posts Blue Dot warning..

[Bugs100]

Alliant Powder periodically reviews and tests their published reloading data to verify that our recommended recipes have not changed over time.

During the latest review Alliant Powder discovered that Alliant Powder's Blue Dot® should not be used in the following applications:

Blue Dot® should NOT be used in the 357 Magnum load using the 125 grain projectile (Blue Dot® recipes with heavier bullet weights as specified in Alliant Powders Reloading Guide are acceptable for use).
Blue Dot® should NOT be used in the 41 Magnum cartridge (all bullet weights).
Use of Blue Dot® in the above cases may cause a high pressure situation that could cause property damage and serious personal injury.

What I don't understand is how they can say, don't use Blue Dot in 41 mag for any weight bullet. but they make no mention of not using it in 44mag..

Because the .44 is designed to handle much higher pressure than the .41?

Nope, they're both SAAMI rated at 36,000 psi.

I agree it's a confusing warning - internal ballistics has always seemed to me to be as much black magic as it is science.
