.350 ball, .018 pillow tick, wonder lube and 45gr 3FFF. Anything around that ought to work well.
This is a good place to start if you want or need to shoot past 25 yards. Less powder than that usually doesn't fair well at all at longer ranges as found on some (ours) trail walks. You will be required to shoot a number of targets ranging from about 9 yards (string cut) to 110yards.
The load that shoots best at 100yards, will also shoot best at 25 to 50yards, however most ANY load will shoot well at 25.
Sight dead on at 25 yards and this will also give 'about' a 50 yard zero - close enough (usually only 1" high to 1" low @ 50) for reactive targets, like gongs.
A charge delivering 1,700fps, will give the following trajectory- or thereabouts.
Note, this chart is developed with the top of the front sight being 1/2" above the centre of the bore. Taller or shorter sights will increase or decrease the rise of the ball between the muzzle and the zero range. (point blank range)

Using 50gr. to 55gr. should run the speed up to about 2,000fps.
These loadings will most likely will be more accurate, with a greased or oiled 'substancial' patch.
This will benefit slightly in reducing the drop at longer ranges.
