intensity cartridges. It is a good choice for .357, .41 and .44 Magnum

NO SMILES!   Primers OK

This powder maybe LOVEX D037.2, I have never seen it and don't know if it is even being shipped to the states or under other names!  The weight suggest AA#9, but it is clearly a different powder (with tear drops, flatten ball and micro spheres) 

[Intercooler]

I will have to look back at the new Federal Trophy Bond pull-down. Similar?

[Intercooler]

Not it! That's interesting... we have another new powder.

I will have to go to basement to look at my AA9.  Will post a pic soon

[The_Shadow]

Osageid, I would welcome your efforts and pictures.  AA#9 did change since Western Powder became the marketing company.  This powder is different than any of the AA#9's I've seen.

I have the older AA#9 which is "Micro Beads" almost black color and the newer AA#9 is "flattened ball" with a gray to silver look.  However this powder has a different texture as mentioned.

[Osageid]

How is this?? Sorry it is with iPhone and not good camera

[The_Shadow]

Yes, that is the "NEW" AA#9 like I have on hand, but if you look you will not see those tear drop and long flattened rods that this powder exhibits.

Osageid, Many thanks...

[Osageid]

You are right!! BTW thanks for all your pull downs:) helps me !!

[The_Shadow]

Your welcome, it helps us all and it is only part of why I like doing the pull-downs.  The main thing is to preserve the history through these documentations.

Now to find out if this powder that Underwood used here is LOVEX or if someone is making a new powder or importing this stuff.  But it is an interesting study!

I think we have a match! Lovex Do32/04 From Intercooler's link

[The_Shadow]

While that picture is in my files the LOVEX data suggest LOVEX D037.2 as a better powder fit performance wise and is similar to AA#9


LOVEX DO37.1 is similar to that of AA#7

[Intercooler]

Do they give a loading/pressure chart for that powder?
