Why no Blue Dot Commercial loads?

[Popeye212]

A good 200gr XTP and BD is 10.4gr
Just work up to it in your gun... my G20 handles it well and it's accurate as I can be.

I use that same load. It's a tack-driver out of my G20, and it gives sub 1" groups at 50 yards from the Banshee. The Banshee bulges the brass beyond re-use, but it's not like I do a lot of target shooting with XTP's anyway.

I've gotten it up to 10.0 and groups started opening up I may go past it since pressure still seems OK.  9.8 is the sweet spot so far.

Earlier in this thread, some posted to Alliant's BlueDot warnings for 41mag & 357mag. BlueDot was reformulated and subsequent testing showed certain previous load data surpassed SAAMI specs.  The loadings in concern can still be loaded with BluDot but with loads reduced from older published data.

Handloader 2009 Feb/Mar has a write up about it.

"In Alliant's case we saw
the purchase of the
smokeless powder division of Hercules, Inc.
by Alliant Techsystems
in 1995 and the resultant move of the
powder manufacturing
facilities from Kenvil,
New Jersey, to the
Radford Arsenal in
southwestern Virginia.
Almost immediately Alliant announced "new
and improved" versions of its traditional
powders such as Red
Dot, Green Dot and
Unique. The new versions were the same as the old in
burning rate and performance
but were much cleaner burning.
As Blue Dot moved to the new
production facilities, changes
were more apparent. Blue Dot
became slightly faster burning."

Hey Trapper, just catching up.. Good info!
I think I know what UTuber you're referring to,.. Did he mention what primer was used in this test?

I've experimented with BD in a number is different cartridges over the years, and found it to be very useful in some way or another with all of them. Of course N. Kalifornia where I grew up and Southern Oregon where I live now, gets cool in the winter, its not as cold as Minnesota

I really like BD in 10mm with heavy cast bullets.
