Shot my RB loads through the Chonograph yesterday. 560 grn RB 1200 fps with really good accuracy.
The 726 grain Parodox slug was doing 1100 fps with accuracy not quite as good as the round ball. These were all loaded with ADI AP100 which is just slightly quicker than Blue Dot.

The load consist of new Winchester 2 3/4" cases, powder, WW plastic wad with the petals cut off over the powder, 1/4 felt wad, projectile and then roll crimped. With the round ball deviation over four shots was 9fps. With the slugs it 48 fps. A bit more reloading still to be done.
