Hey guys. The bulk of reloading I do is .38/.357 and .44 mag. For both these cartridges I use Clays (fast) and AA#7 (slow) for target and full power loads, respectively. I've noticed with either powder it's near impossible to get every last bit out of the measure. I keep a good eye when it's throwing charges and make sure the mix comes out homogeneous but for the sake of argument lets say a few flakes of Clays (not grains but individual flakes) gets mixed in with a full magnum charge? Will this sort of low-level cross contamination present an issue?
