    Default IMR 4064 vs XMR 4064

    Can you use these 2 powders interchangably? I never do, but these look to be near identical and they are side by side on the burn rate chart. ANyone have a comment?

    Thanks,

    Matt

    No one is going to go out on a limb and tell you to use two different powders interchangeably.

    I will go so far as to say if you have data with one of the 4064's you might consider it's lowest starting charge and work up the other with traditional methods. A phone call to the manufacture may be an option if you don't have any data.

    XMR4064 is also known as AA4064

    Thanks Marshall,

    I figured Someone would have interchanged these 2 powders. The big question is what is the ratio of energy vs density. If those are similar, and we already know they are next to one another in burn rates then they should be close enough to start low and try both...and pay attention.
