Thanks for the info. I was wondering this as well. Anyone tried 150 grains of powder? Or 3 Pyrodex pellets? I'm thinking I may try that with a either 245 or 295 grain Powerbelt to see how it does. I'm hoping it will make a decent long range gun. As in 150 yards or so. Maybe even 200 yards. Although I'm not sure I have a place to sight them in that far away. My place to sight them in is only 100 yards. I've got a buddy with a field that's probably close to 200 yard though.
