Jukar .45 cal fullstock

[Ricklin]

A friend gave me this old muzzleloader, only markings on it are Jukar and Spain, It has a full stock, brass furnitue, and .45 cal.
I cleaned it up, it's a pretty low quality piece, but looks to be safe enough to shoot. Approx. ball size and charge would be helpful gang:) Anyone else seen one of these / know anything about them?

.440 ball, .015 patch and around 70 grs. of powder to start. You may have to play with patch/powder combinations to get it to shoot its best.

There are literally thousands of such guns. CVA was the primary, if not sole, importer.
