With the advent of all these new powders, the current manual is of limited use especially on slug data. Slug data is also very scarce with data from the other powder venders for slug loads.
The powders listed by Lyman for the 20 gauge sabots are so limited and use discontinued powders as to be marginally useable.
What's the solution? Do we put pressure on the powder manufaturers, establish our own data base on castpics or live with it.
Love to see some Herco, Longshot, Unique and HS-6 data for 20 gauge 2 3/4" cases for the 20 gauge with the sabot slug.
Any help appreciated. PM experiences if you don't want to publish./beagle
