Only opinions here Sj. I think unique is an outstanding powder, and a really nice option to have for nearly any cast bullet fiddling. I suspect you will want to try your new rifle way out at long range, and may look to other powders.
I would be a little hesitant to assume black powder is just dumped into a case and fired. Folks are using all manners of wadding, duplex loading and compression that might make the powder seem like a semisolid block. Maybe, start with something like the Lyman manual, then branch out as you become familiar?
edit to add Brent, most schuetzen shooters are using relative small bore rifles and exclusively smokeless powders, fast pistol type powders.
