I think there is an error in QL in "Burn Rate Factor" for the 4350s. QL has H 4350 listed as .4750, IMR at .4801 and AA 4350 at a woppin .3810. Hell, thats slower that R-22. Any idea as to why it is listed so slow? Do you think this should be .4810 instead?

Thats the burning rate at ignition of the outer layers of the grain. Due to totally different surface treatment these values are not comparable. There exists no single "burn-rate" for any surface treated propellant (other than "green-corn" which is not available to handloaders).
