that Cor-Bon typically uses powders specially formulated for low muzzle flash so you should be fine in that respect. I used to carry Cor-Bon 200gr.+P loads exclusively but changed a couple of years ago. I now use the Taurus Hex Bullet 185gr. solid copper. It gives equal expansion, if not better, in a standard pressure load. There's less felt recoil and muzzle flash. There's nothing wrong with the Cor-Bon load but if you can get the same performance without beating up your weapon, to me, that's the way to go.
