I few years ago I was given 30 pounds (yes 30) of Herters 164 shotgun powder. I did get a one page sheet of shotgun loading data with the powder and have worked up 12 and 16 gauge loads and I am happy with them. 164 seems to be in the same burning range as Herco. That sheet also had data for the other Herters shotgun powders 160, and 162. If anyone needs that information I would be happy to post it. I would be interested in finding if Herters ever had pistol loading data for this powder in any of their reloading manuals. Since I have a lot of it that could be useful in loading 38spl, 9mm, and 45acp. Does anyone have old Herters manuals that might have this information?
Herters rifle powders were made in scotland and I have read that the Scott rifle powders are the same as the Herters rifle powders. If that is true I would think that their shotgun powders might have been made by them also, and if that is so, Solo 1250 maybe an updated 164. It might give me a starting point for working up some pistol loads.
Thanks for any information you might be able to help me with.
