I don't think much of using that tissue. Some folks do it and get away with it, but there have been entirely too many reports of ringed barrels for me to ignore them.
You've got the right powders for what you are doing. They have been used for reduced loads as long as they have been around. XMP 5744 and either of the 4198s are also good. Never heard of a blowup with reduced loads with any of them.
