Had a hard time finding VV320, 330, and 340 lately so I'm searching for other powders to use that might also be single-base like the VV. In that search I ran across Accurate Solo 1000
and Solo 1250
which seem to be in the same speed ranges.
The Accurate pamphlet describes the Solo powders as "pistol powders", but there are no loads in the booklet for Solo 1250. When I inquired to the Western Powders hot line I got a reply from Johan Loubser saying that, "Unfortunately the Solo1250®has been discontinued." No load info was offered.
Of course, the reason for my inquiry was that I bought 1-1/2 pounds at a gun show last weekend.
