Lazarus,

This isn't really pointed at you, but rather everyone who posted something similar.

You are right, it doesn't seem logical! But consider this, don't you think the manufacturer of any product must have a really good reason to publish such specific recommendations/warnings about their own product? This is certainly not something the company would take lightly.

Witness Hodgdon and Winchester for years claiming there was no problem with reduced charges of H-110/296 in spite of masses of anecdotal evidence that guns were being blown up with reduced loads. That situation did not seem logical either, but it is widely known now that this does happen and both manufacturers now publish a strong warning about reducing loads for this (for H-110/296 are identical, same manufacturer), Winchester recommends not reducing more than 3% below their published maximums, and Hodgdon uses 5%. Both publish only a maximum load!

You, and anyone else, can do as you please with the warning, and I know you will. It seems to be, at the very least, exceedingly imprudent to not only argue/disagree but disregard and advise others to do the same concerning a warning issued by any manufacturer about it's own product.

FWIW, I have loaded Blue Dot in virtually no cartridge EXCEPT .41 Magnum for about 35 years with no problems whatsoever. There are other propellants which will do as well, possibly better in this cartridge than Blue Dot, why not accept their warning? It certainly was not issued frivolously or without much corporate soul searching!
