I would have to say the warning is highly unusual. It's hard to convince me there is a problem with one bullet weight in .357 Mag and all .41 Mags and nothing else has been affected.

I would also think there would be lot numbers that are recalled if the problem exists in recent production. Powder from 2004 should have exhibited problems long ago or people have been using a potentially dangerous product for 5 years without knowing it.

It all does nothing to instill confidence in Alliant's products or their addressing the situation in a timely manner. That's just like their failure to warn of the propensity of Blue Dot to exhibit high pressure problems when the ambient temperatures get lower than 0 degrees F. That was confirmed by a phone call where I specifically asked about how low the temperature needs to get for the problem to arise.
