Im pretty sure that knight is the one that sells the sabots. Usually you would get a .500 dia bullet or a .452 bullet. The .52 were made for the .500 dia bullet though. Bullets are pretty expensive. I'm selling my .54 renegade LRH 1:24 gun if your interested. Then you don't have to sell your other guns and still shoot the .500 dia bullets. Send me a PM if you interested.
