Not to totally get off track, but if you like to roll your own, try Vihtavuori N350 in your .357Sig or 10mm. Am friends with the owner of the range I use and we were doing low ambient light shooting after he closed the range for the day. (I don't shoot too much around the house, just enough to keep away the meth heads or dispatch coyote. Occasionally, if I'm tinkering, I roll off some bursts).
Anyway, we shot some AA#9 which is a good powder but blinding. The Vihtavuori has a remarkably reduced muzzle flash. Just throwing that out there.
