I think that might work, but you may end up with lots of fouling with light loads in such a large case. W231 comes to mind, but if I didn't have any I might give W244 a try. I've never used it, but I believe it's supposed to burn cleaner than 231 based on reading a bit of ad copy.

I wish you luck!

Don't be the darkness.

America will perish while those who should be standing guard are satisfying their lusts.
