I did a search on this forum and went to Hodgdon's website, checked the burnrate chart, winchester website i can't find out anything on win act pist, WSL, WAP is in my loadbooks usa manuals. Did they change the name of these to something else?
Yes, According to Johan Loubser at Western Powders, Ramshot Silhouette is the exact same powder as WAP +/- a few new coatings to reduce flash. According to Johan, data is interchangeable, but it's best to use newer Silhouette data.
SOme of the older manuals have data for them, why I never throw them away. What caliber?

Winchester brand powders are St Marks Powders and share the same nomenclature for the numbered Winchester powders, ie W231 is SMP #231. I'm compiling a chart of all the commercial and non-canister powder types for reference.
WAP is identical in character to Ramshot Silhouette and data will interchange. The Silhouette has additional flash reducers blended, but does not change the burn characteristics. I'm trying to track down the OEM non-canister nomenclature for this one.
Auto Comp is #224
Titegroup is #242
Lil' Gun is OBP516
W760 is #760 also sold as H414
W748 is #748
WSF is WSX170
HS6 is #540 also sold as W540
HS7 is #571 also sold as W571 and reformulated to be Longshot which is now called OBP473
WST is WAA90
Linear Mode
