Seems kind of high. My 54 cal wasn't unfired but it was in very good condition 1.5 years ago for $165.00. Sold it 8 months later for a bit more but not close to $300.00.
For a NIB never fired, $300.00 is on the high end. The Renegade has a 1-48 twist barrel and shoots roundball very well. It also shoots conicals and sabots as well. They are a great hunting rifle. Is this the Renegade or the Renegade Hunter? The Renegade Hunter has a single trigger while the original Renegade has a set trigger/double trigger system. They are very good rifles.
