John's (MrKTI) earlier post re-instated below, we had a minor glitch, the Mods.
"You are about to get 234 responses saying W231 is the hot set up ... and one person (me) saying try True Blue. I bought some to load 5.7x28, and decided not to load them, so I have some True Blue laying around.
Not the best choice, but I just hate being the only one ...
MIght be more available too.
True Blue is a slower powder than W231, and I am now using is for .380 up thru .357. Seems the recoil is more gentle but that's probably just me.
TB is a ball powder like w231 so meters very well.
Just tossing out a contrarian point of view ..."
