Two great cartridge choices for an XP.Gabe has suggested some great powders too,I would add Rel 7 for the VT and N-135 has proven to be very accurate in my Dusters.As I run out of my VV stash I am switching back to the more temp insensitive powders,enjoy them.

As everyone knows, some powders are hard to come by. For my VT I'm using AA 2200, AA 2230 or RL 7.
