I'm trying to select a different powder for my .243, and one of the traits I'd like it to have is that it meters easily and consistantly, thus making a ball powder (i.e. H-380) preferable over a short extruded powder (i.e. Varget), which is preferred over a long extruded powder (i.e. IMR 7828). Then the thought occured to me that, while I have seen list after list of powder burn rates, I have never once encountered a list that states what type of powder each different powder is. (i.e. H-380=ball, Varget=short extruded, Universal Clays=flake, etc...). Obviously they won't let me open the containers of all the powders I'm interested in at the store, so I am at a loss as to how each powder is shaped.

So what I'm interested to know is:

A.) Does anyone have a list of each powders shape they can post or direct me to?

OR

B.) Can you post a list of powders you've used with this information?

Here's the ones I know from experience:

U. Clays = flake
H-110=flat ball (or maybe flake, hard for me to tell)
2400=flat ball
Varget=short extruded
VV N110=short extruded
IMR 7828=entruded
H-380=ball

Thanks,

Mike
