I put a set of fire sights on mine, you'll have to file down the dovetail on the sights though, the metric dovetail is smaller than the standard inch size. The biggest problem with the .495 balls is usin' the thin patch, it might burn out. Other'n that, it oughta be safe. I'll go along with the loose powder idea though, and real black is cheaper, even with the hazmat fee for shippin' the danged stuff. Just buy 10 lbs at a time, mix the f grades up to make up the shipment. My rifle prefers the FFFg to the FFg, and Grafs pay the shippin'.
