Powder in the Blender
« on: January 29, 2014, 05:45:57 pm »
So I was just thinking of things to do.  I've been selling a lot of loading powder lately and one thing that people have been asking for is for Hodgdon H4831sc.  The H4831sc is identical to H4831 except the sc stands for short cut.  It has shorter grains of powder.

Could one safely take the regular H4831 and stick it in the blender and make your own "short cut" powder?

The only reason people like the sc version is that on some loads, the cartridge is very packed.  They can get more powder in there.

What do you think?  This is just a fun mental exercise.

    You change the size of the grain, you change it's burn rate.
    The result is higher pressure.  Dangerously so.
    The SC is not the same thing just cut shorter.  It actually has a different burn rate so that the smaller grains burn at the same rate as the larger grains.

    Hodgdon says they have the same burn rate in their chart.  Both are listed at 100.  But I think I know what you are trying to say.

    To rephrase what George said: They both have the same burn rate as they're sold (one cut long and one cut short), but they aren't the same chemical blend and if you alter one it will absolutely change its burn rate.

    Not to mention that putting smokeless powder in a blender would run a good chance of having it ignite. Needless to say, that could have unpleasant consequences.

    But you would make up for it with money from YouTube if you record it.

    Even if you didn't have to worry about ignition in the blender what would really happen is that the sticks would get pulverized or at the very least there would be a lot of inconsistency with the cut that the burn rate would be all over the place.  Stick powders are run through an extruder at the factory and it's cut at pretty precise lengths so doing it yourself would be a bad idea to just buying the powder that you want in the first place.

    So now you know.

    As a mental exercise, this is what is known as NOT-A-GOOD-IDEA.
