I'll tell you about a substitute.Grafs has the now discontinued Winchester WXR powder on sale for 15.00 a pound or 110.00 for an eight pound keg.I've been using it in a 7STW and 300WSM and am in the process of working loads for 270 and 7mag.As far as I can tell,it's the same powder as Reloader-22.It's double based,made in Sweden,most like the same factory just different packaging.It loads the same,chronographs the same and I've achieved one ragged hole groups with this powder in my rifles.At that price,you cain't go wrong and I think you'll be quite happy with it.
