Can any one with swift load give me an approximated velocity guess. If its linear I can just do the math but I am guessing force curves are not (for this reason curves).
possibly they did a thing magical towards the retardant that they coated the tubes with, but if not, then chopping the spherical tube into lesser items so it meters much better and packs tighter in the situation will give the identical volume of powder far more burning area, Therefore the melt away will probably be a bit faster.

Oscar, I really believe the burn up rates will not be exactly the same, exact as distinctive plenty of the identical powder might have distinctive burn premiums.
