Jerry,
I have it from the importer that it is the same exact powder as Xterminator. I have shot it enough to know that it can be accurate, is the velocity seekers friend, and that it burns fairly cleanly. I tried it because a friend told me that he and a shooting buddy who had tried a number of powders in their PPCs and upon later review of the groups that they had shot over time, were surprised to learn that the winner was Xterminator. I normally do a one shot per charge investigation at about a .3 grain interval, up to the point where the bolt gets snug. If you do this over a chronograph, on the same target, starting at 29 gr. I think that you will quickly find a load and be pleased by the velocity that is possible. The powder is produced in Belgium, and the supply has been pinched for a while because of a fire, but recently I have seen some for sale from one source.
