Anyone have one with the .25 barrel and if so - you shooting slugs with it? I've been having "pretty good" results with H&N 34g ( .250's ) @930-940 fps but hoping to find something that will perform better. The new one ( Prophet II ) apparently uses the newer "hybrid" barrel that might be better for slugs (?). I see that RTI is going to sell that new barrel separately - just wondering if it might be worth it or if any of you have already found a decent slug solution for existing .25 barrels.
