Seeking an opinion on a "bog standard " shotgun powder.

Thanks to the kindness of several members, I now have the ability to re load BP 12 gauge for my Hollis and Sons s/s. It occured to me that it only requires a different powder to also load for my o/u Laurona.

SO I seek an opinion on a suitable general purpose powder, nothing special, just for shot and sabot slug.

Thank you.

Now sorted.........
